TEXT. The inf'luence is investigated of thIPcrystallizing
and free water an the magnetic stisceptibility of paramagnetic and
diamagnetic materials which crystallize with a certain number of
water molecules. The authors report on measurements of
magnetic susceptibility of aqueous solutions of CoCl 2' 6H 0,
FeSO -711 00 lCaCi -6H 0 iihich are represented by a broken fine of

three sections, an unbroken line and a curve in that order and
offers an explanation for the found behaviour. The authors
recall that-Wiedeman (1868) and K8nigsberger'(1899) observed the
discrepancy which exists between the measure(] magnetic suscepti-
bility of salts in solution and the value calculated from the
susceptibility of the crystalline material and,survey some of the

G~ I. Kruglyakova (Doklady AN SSSR 193, 1958, 443) is considered
and extended to a diamagnetic material not so far investigated.
The water content was 0 to 1000%. Specimens with low water
content were obtained both by moistening and drying - identical
results being obtainecl in both cases. 'The measurements were

regions of dependence of magnetic susceptibility on water content,

TITLE: '1h" influence of therrital.. and ultraviolet radiations
on the nuclear magnetic resonance of sodium
polymethacrylate
PPIU01 0v
DICAL: ~eskosl ensky casopis pro fysiku, no.3, 196z, 205-2j5
TLXT: An installation for oscillographic study and automatic
recording of the differential nuclear magnetic resonance
absorption curve is described. A, rather high curve broadening
to 0,085 Oe-was attributed to poor field uniformity produced by
the magnet of East German origin. However, the apparatus gave
adequate resolution for the study of the influence of the thermal
and ultraviolet radiations on sodium polymethacrylate
containing 40% w1w water. specimens of the latter were studied
prior to, and at various time intervals after exposure to*
radiati4on. - The intensity of the absorption line immediately
and 18 min after thermal irradiation of 3 hours duration was
found to 3.33 and 0.'82 times respectively of theintensity before
irradiation. Within the same 18 min, the line broadened from

0.556 to 0.750 Oe, while the temperaturedropped from 90 to 220C.
These and similar phenomena were explained by the gel character
of sodium polymethacrylate. It. was contended that when the
specimen is dehydrated it loses all its elasticity and also the
magnetic resonance whicks is attributed to the hydrogen nuclei of
the.water retained by sodium polymethacrylate. The.author infers
that the sample has a colloidal structurie. This comprises the
long chained molecules of sodium polymethacrylate proper
surrounded by a layer of highly oriented dipoles of water
molecules which adhere tightly to the surface-of' each polymer
molecule. , Further outward, there is another less oriented and
less tightly adhering second layer of water molecules and
finally. a free and completely diffused suspending medium of
water solvent. In this way the decrease of' absorption line
width dud to irradiation is explained by the increased
its layers.,
molecular motion in the solvent throughout all
Whereas from theoretical considerations the width intensity of
the absorption line should be a constant, in thiscase its value
varied, viz it was 1.85 immediately after the thermal

irradiation and 0.613 18 minutes later. Hence the increased
inten~iity cannot be accounted for entirely by the decrease in the
width. The discrepancy is thought to be due to the increased
vibration of the oriented dipoles in the first layer of water,
which increases the nuti-iber of resonating hydrogen nuclei. The
final decrease in the intensity of the absorption line to
it level
below the irradiated value is probably due to an overa 11 increase
in the number of dipoles over their original number. It is
concluded that the effects of the ultraviolet irradiation are
similar to that of the thermal irradiation, although the
temperature during irradiation did not change. There are.

potential of '.5 to 7s.0 V. These jumps in potential and the
chemical reactions due to.them are.explained by the changing
surface finish of the electrode and the influence of
intermediate platinum compounds. There are 8 figures and
