Note on the Fluorescence Spectra and the Fluorescence
Action Spectra of Some Proteins (Spektry fluorestsenteii
i spektry deystviya fluoreateentaii nekotorykh belkov).
PERIODICAL: Doklady AN SSSRI 1957v Vol- 116, Nr- 4, P-P. 594-597 (USSR)
ABSTRACT: The present paper contains experimental data on the
determination of the centres, which are responsible for the
fluorescence of protein and for the iutramolecular
migration of energy in albuminous substances and in
nucleoproteides. In order to clarify these problems the
authors determined the spectra of fluorescence and of
fluorescence action of albuminous substances and of
mixtures of amino acids, of which they are composed. In
both cases the fluorescence was excited by mercury quartz
lamps of the type xPK -2 and xPK -7. The fluorescence
radiation was received by the antimony - caesium photo
electric cell of the spectral photometer Cf -4. The
execution of the measurements is discussed shortly. In the
case.of a few albuminous substances (which are enumerated

fluorescence spectra with two maxima at 313 ane 350 m~4-
These spectra differ & little from the spectra found in
a preceding paper (reference 3). The first of these spectra
comes from tyrosine, the second from tryptophane. A mixture
of aromatic amino acids with the same ratio as in the
albuminous substance under investigation furnishes the
spectrum of the corresponding albuminous substance in a
qualitative respect. Hydrolized albumin also furnished the
same spectrum. Albuminous substances containing no
tryptophane and dipentidglyziltyrosine furnish a fluoree-
cence spectrum showing only one maximum. These and other
facts speak in favour of the fact, that only the aromatic
amino acids are responsible for the fluorescence of albuminous
substances. For the purpose of studying the problem of the
possibility of an energy migration into the aromatic amino
acids from other components of the protein molecule (in
particular with a peptidic binding) the spectra of the
fluorescence action of albuminous substances, of their
hydrolysates and of mixtures of the amino acids, of which

TITLE: The Activity Spectrum of the Fluorescence of Albumins
(Spektry deystviya fluorestsentsii belkov)
PERIODICAL: Izvestiya Akademii nauk SSSR. Seriya fizicheskaya, 1959,
Vol 231 Nr 1, PP 90 - 93 (USSR)
ABSTRACT: The author had shown that the fluorescence of albumins is
composed of the fluorescence of the aromatic amino acids
phenyl alanine, tyrosine and tryptophane, that in native
(untreated) albumins the intensity of tryptophane by far
surpasses that of the others, and that this effect becomes
weaker in hydrogenized albumins. From the invariability
of the fluorescence intensity of casein in the case of
excitation with various wave lengths, it was concluded that
the quanta absorbed by various amino acids excite one and the
same fluorescence center of the albumin, i.e. that in the
interior of the macromolecule a migration of energy between
the amino acids mentioned takes place. A table shows the
spectral composition of casein fluorescence in the case of

the spectrum of activity for casein at various pH values, ana
the absorption spectrum for casein, native (untreated) in
phosphate buffer, pH=8.2. and after 3 minutes' denaturation
at 620, are shown by figures 1,2,3. The following experimen-
tal specialities were found: in native (untreated) casein
there is a maximum at point 243 mg which vanishes both in
slightly denaturAted casein and also at a pH value7 9. The
absorption spectia of native (uptreated) and denaturated
casein are nearly identical. In no case is there.any shifting
of bands. The following conclusions are drawn from these
facts: Absorption of light having a wavelength of 240-245 mg
by the peptide binding with transition of an atomic group
-CO-NH- to an excited singlet level. Transition from the
singlet level to a triplet level (conductivity zone) Of
the albumin. Passing of an electron from the conductivity zone
to the aromatic amino acid, emission of a light quantum.

a resonance migration of energy between the individual
amino acids, as well as of an electron migration of the
type of activated semiconductors from the peptide binding
to the aromatic amino acid. There are 3 figures, 1 table,-
and 6 references, 2 of which are Soviet.

ABSTRACT: On the basis of experiments of various authors it can be
concluded that the scale on chromium oxided in oxygen
as well as in air consists of rhombohedric Cr2o 3*
On the basis of indirect indications the
assumption was expressed of the existence of y-Cr 203
but this has not been established experimentally.
The*influence of the air nitrogen on the process of
oxidation has not been taken into consideration by
previous authors although in principle su6 an influence
is possible at elevated temperatures. In other work of
one of the authors (Ref,5) formation of a nitride was
observed on the X-ray diffrastion patterns as a result
of nitriding of'chromium which was similar to that
interpreted-in earlier work (Ref.4) as a sign of
presence of y-Cr203,, For getting a more accurate

investigated the oxidation of chromium in air and in
oxygen. At various temperatures the kinetics of the
scale formation was studied (from the gain in weight of
the specimen) and also the phase composition and the
texture in the layers of the forming scale (by X-ray
diffraction) and ' the microstructure of the layers.
The specimens of electrolytic chromium were made in the
form of hollow cylinders by a method described in
earlier work (Ref.4). The oxidation in air was effected
in a vertical electric furnace whereby the specimen was
suspended on a tray of an analytical balance located
above the furnace so that the weight increase could be
determined without removing the specimen from thehot
part of the furnace. Oxidation in oxygen at a pressure
Of 160 mm Hg was effected in a closed vertical quartz
tube placed inside a tubular electric furnace; by means
of a special gate the specimen was displaced from the
top, cold part into the hot part without disturbing the
atmosphere,14the tube and,after a fixed oxidation time,

ABSTRACT: Arkharov et al. (Refs 1-3) found that three layers of
chromium carbides or 3C21 Cr703 and Cr23 C6 (one on
top of the other) are formed in carburization of
chromium. Studies of oxidation of chromium in air
(Arkharov et al., Ref 4) showed thatothe atmospheric
nitrogen reacts with chromium at 700 C and higher
temperatures, forming a layer of chromium nitride under
the oxide layer on the surface. Nitrogen was found to
affect also carburization of chromium. To investigate.
theeffect of.nitrogen on diffusion of carbon in
chromium, the author studied carburization of chromium
in an atmosphere containing nitrogen (carbonitriding).

of various layers formed on chromium were studied.
Electrolytic chromium was used in the form of small
cylinders, employing the technique described by
Arkharov and the author (Ref 3). Chromium samples were
carburized in a vertical tubular electrical furnace
in a moving atmosphere consisting of a mixture of
benzene vapours with nitrogen. The composition of the
gaseous mixture was determined by thermostattingthe
temperature of the saturator with benzene through which
a stream of oxygen-free nitrogen was passed at the rate
of 10 litres/hr. Study of the carbonitriding kinetics
and metallographic investigations followed the technique.
described by Arkharov et al. (Ref 4). Carbonitriding was
carrW out at the temperatures of 700, 900, 1000 and
1100 C. The microstructure of carbonitrided chromium
showed clear laminar structure due to diffusion of
nitrogen and carbon into chromium. X-ray crystallographic
analysis indicated that the layers had the following
Card2/4 compositions:

3. An inner layer of hexagonal CrA
In weakly carbonitrided samples Of "bright" chromium,
Cr2~ layers have a clear texture of (110) type parallel
to the external surface. With increase of the duration
of carbonitriding, the intensity of the maximum in the
X-ray diffraction pattern, due to Cr,:,N, decreases and
the intensities of the Debye rings of Or 7C3 and Cr3 C2
increase. Carbonitrided samples of "grey" chromium
show no sign of texture. The absence of texture in
the external layers and the absence of loose structure
at inter-phase boundaries indicate that nitrogen and
carbon diffuse through the surface layers towards metal.
There is hardly any diffusion of chromium in the
opposite direction. The presence of a nitride layer
under two carbide layers shows that the rate of diffusion

in chromium. A similar effect is observed in oxidation
of chromium in air (Ref 4). Under simultaneous
diffusion of atmospheric nitrogen and oxygen, the reaction
front of nitrogen overtakes the reaction front of oxygen.
A layer of chromium nitride is thus formed under an
oxide layer. The author found 8hat diffusion of carbon
and nitrogen in chromium at 700 C follows a power law
AM = Rt", where n = 1/3. With increase 06 tempera-
ture, the value of n increases and at 1100 C it
approaches 1/2. At all temperatures the rate of
carbonitriding of chromium is faster than the rate of
carburization. and it is not slower than the rate of
nitriding of chromium in ammonia.

ABSTRACT: Nitrogen participates in the diffusion of oxygen or
carbon in chromium at high,temperatures. In the present
work nitriding of chromium in an atmosphere of ammonia was
studied. The kinetics of the process, phase coxposition,
texture and microgbruoture of the nitride layers was studied
during their formation at various temperatures between 600
and 120000. Electrolytic chromium served as the basia
material in the study. Spealmen3 were made by Arkharov's
method (Ref.14) in,the shape of hollow cylinders, 17 am long,
7 mm diameter and 0*8 ma wall thickness. Deposition was
oarried out by two different methods, giving two diff*rent
types of coating (Ref.15) - (1) bright chromium de osits,
having a well-defined texture, and r2) matt (grey7deposits

in a closed-vertical quartz tube placed inside a tubular
electric furnace. Before and after nitriding the specimens
were weighed and the increase in weight determined. Debye
crysballograms of the phase analysis were taken in K-Cr rays
after asymmetrically blocking up the film. Textural X-ray
pictures were taken and interpreted by a method described by
Arkharov (Ref.16). For the metallographie study chromiun
deposits were prepared on steel cylinders on which flat
portions had been filed along the generatrix. After
nitriding, oblique sections of these flat portions were
prepared for micro-examination. In Fig.1 the dependence,
of weight gains of specimens at various temperatures on
duration of nitriding is shown. Fig.2 shows the temperature
dependence of the angle of inclination of the kinetic curves
for nitriding of chromium. Ln Fig.3 a micrographic cross-
section of a chromium specimen after being nitrided right

Investigation of Diffusion in the System Chromium,Nitrogen
The results obtained in the above investigation have led
to the following conclusions:
(1) The reaction diffusiog in the system Gr-N begins with
perceptible speed at 700 0 and obeys the para8olio time
law in the entire temperature range up to 1200 G.
(2) As the temperature is increased, the diffusion rate of
the Gr-N increases initiall lowly (i.e. below 103000),
then rapidly ~above 1030OGT.s
(3) Below '41.030 C -nitriding produces a two-phase layer in
chromium - an internal, thicker ona of Cr2N and an outer,
thinner one of CrN1. Above 10300C only the Gr2N layer
is formed. The OrN phase is unstable in an ammonia atmos-
phere above 10300C. It does notre-form and the phase CrN,
forming below 103000, is converted into the phase Cr2N as
this temperature is raised. The change in increase in
the diffusion rate with t-emperature at above 10300C seems to
be associated with a change in the nature of the phase in
the diffusion layers.

(51 The outer layer, CrK (forming at below 103000 never
possesses a texture, irrespective of whether the chromium
and the Cr2N layer, have.a texture or not.
(6) All structural characteristics of the layers point to
the fact that during reaction diffusion in the Or-N system
nitrogen diffuses from without through the nitride layer into
the metal., and no perceptible diffusion of the metal occurs
in the reverse direction.

studies of diffusion with reaction should involve
mixtures of gases as well as of solid phases. The general
aim Is to study such diffusion (especially gas.corroslon
and processes for making high-temperature coatings) and
find practical methods of regulating these processes:

relating to those in Fig 1, where the curves become

were subjected to qualltative X-ray analysis: a feature
was the appearance of a new phase. Fig 3 shows lines from
the outside (a) and inner (6) layers of a specimen

ABSTRACTs it was observed by the present authors, in the course of
an earlier investigation (Ref 10), that qualitative
phase analysis of the products of reaction between
chromium and sulphur, taking place under identical
conditions, sometimes gave different results which
indicated the possibility of the structure of these
products being affected by the cooling rate. The object
of the investigation, described in the present paper,
was to check this hypothesis by studying the effect of
the cooling rate on the structure of chromium sulphides
formed at elevated temperatures. The experimental
materials were prepared from chromium and sulphur powders.
The carefully weighed and mixed charges, placed in sealed
evacuated quartz ampoules, were inserted in an
electrical furnace, heated slowly to the test temperature

there is a preferential diffusion of nitrogen and carbon
atoms to the metal through the reaction products,
Nitriding is quicker than carburization and the rate of
the combined process Is intermediate with nitrogen

ABSTRACT: This is a further contribution to the series of
researches by this school on diffusion with reaction
in systems of the "metal - mixture of two chemically-
active gases" type (Refs 1-7). In the work the authors
extended their previous experiments on the chromium-
sulphur system (Ref 10) before proceeding to the ternary
system with nitrogen. Hollow cylindrical (sometimes
parallekpiped) specimens of electrolytic chromium were
suspended by quartz in a furnace (Figure 1). For the
binary system the heated vertical quartz tube was
evacuated and its lower end was kept at 250 0C to give a
sulphur vapour pressure of 12 mm Hg. For the ternary
system.the tube after evacuation was connected to a source
Cardl/3 of pure nitrogen. The products were examined as described

carried out at 700, 800, 900 and 1 000 0C at a constant
sulphur partial pressure; nitrogen pressure was constant
at 25 to 30 mm Hg (gauge). Table I gives the number of
layers detected metallographically, the results of X-ray
phase analysis, presence or absence of texture and the
microscopic characteristics of the diffusion mechanism.

In the binary system the outerlight layer approximates
to Cr 2S3 at 1 000 OC and Cr 3S4 at 7CO OC, while the dark
inner layer approximates to Cr 5S6* The work showed that
in this system the reaction diffusion involves movement
of the components in both directions through the scale
layer, the relative importance of chromium growing with
increasing temperature. In the ternary system the process
depends on diffusion of sulphur and nitrogen through
crystal lattices to the metal and of chromium to the scale
outer surface. There are 6 figures, 2 tables and

TITLE. On the joint diffusion of two elements Into solid metal

TEM A theoretical analysis is made of the joint diffusion of 2 elements
into a third one in systems of a solid metal and a mixture of two chemically
active gases: Me - (XI + X"). Phase diagrams of the systems formed by compounds
which exist in the binary systems of the Me-X type, are classified. Cases are
analyzed where the solubility of Xt and V is unlimited, limited and absent in
the binary compounds of the pseudo-binary system MerXim - MepX" q. In the first
case the diffusion layer consists of a single phase with a concentration gradient
decreasing along the depth of the layer for both components. In the second case
the surface layer consists of a phase with a higher content of the element with
least diffusional mobility. At a certain depth a layer of another phase may
exist with a higher concentration of elements with a greater diffusional mobility.

In the 3rd case on the metal surface first a layer is formed (or layers) consist-
ing of phases which exist in the binary system: metal-element with a high
chemical affinity with the metal. If V and X" interact, then the process will
be determined and regulated by the reaction of.the metal with'the excessive
element and with the phase of gaseous components formed again, The mechanism
of diffusion in binary systems affects the diffusion mechanism in the system
Me-(XI + X") . Some factors are studied which affect the kinetics of the processes.
7-hie second case is experimentally confirmed by V. N. Konev and V. I. Arkharov
and others (RZhMet, 1959, no. 11, 24702; "Piz. metallov I metallovedeniye"
1952, v. 5, 192). The first and third case were not specially studied.

TEXT: An analysis of vario,is structures found in the diffusion
layers of diffusion-reaction productag within systems consisting of
metals in the presence of two chemically active gases, was carried
out. Structural pictures of diffusion-reactions were obtained for
the systems Cr-09 Cr-Cq Cr-Nq Or-39 Or-S-Np Cr-S-0, Cr-N-O and Or-N
-C. The structural pictures obtained were tied up with general -the-
ories on the reaction mechanism of complex systems of the above ty-
pe. It was established that it is possible ii- principle to use dif-
fusion-reaction layers in 'the systems Cr-Cq Or-C-N, Cr-O-S as pro-
tective coats., There are 1 figure, 1 table and 4 Soviet-bloc refe-

TEXT: This work deals with reaction diffusion in the systems
W-C, W-N and W-C-N at temperatures up to 12000C including kinetic
studies of carbiding, nitriding and carbonitriding and X-ray *
determination of the phase composition of the products. It is a
continuation of the work of these and other workers of the Arkharov
school in this field (Ref.1-9). No such investigation on the
W-C-N system has been reported. For W-C reaction diffusion was
effected by previously described methods (Ref.8,16). The reaction
with a paraffin-hydrogen atmosphere starts to become appreciable at
10000C and? as do the other reactions studied, it follows the
parabolic time law up to the maximum temperature (12000C). The
outer layer was found metallographically and by X-ray diffraction
to consist of WC and the inner Of W2C- No texture in the first

investigation of Reaction zili/E435
was found. The diffusion was uni-directional, from gas through
scale to the metal. Reaction of tungsten with ammonia in a
previously-described apparatus became appreciable at 1000*C, giving
an outer layer of WN and an inner Of W2N- Additional experiments
confirmed that the upper temperature limit for the existence of
these phas'es in an ammonia atmosphere is 1100 to 12000C. For the
ternary system, the method was similar to that previously used
(Ref.3,8). X-ray diffraction showed that the diffusion layer on
tungsten annealed in a mixture of paraffin vapour and ammonia is
again WC and W2CI but the presence of nitrogen in the atmosphere
(although carbon partial pressure is unchanged) retards carbon
diffusion in tungsten. This is contrary to observations on
Cr-C-N (Ref.3,4), MO-C-N (Ref.8) and Fe-C-N (Ref.20) and is not
explicable in terms of activation energies of diffusion for carbon
and nitrogea. The authors conclude from their diffusion studies
on W-C-N systems that there in preferential diffusion of nitrogen
and carbon through reaction products in all th~ase systems.
