ABSTRACT s ~~ The.artiole.deals.with the use of nuclear paramagnetic
~.radiofrequenoy.reeonance for isotopic analysis on the
basis of a formula derived by Bloch (1). This formula
determines the magnitude of.nuclear paramagnetic resonance
absorption under condition of slow transition through the
resonance*
The author points out that the magnitude of resonance
absorption effect depends essentially on relaxation times,

the. icochrcmatic lines and of the stress distribution confirm
the assumption'that the orientations parallel and vertical

This implies that the silver chloride platelets with a rol-
ling or pressing structure are either orthogonal isotropic
or orthotropic (Ref 6). ThereAs reason to believe that the
radial and,~sector-shape nature of the ~soclines substantiates
the assumption of a radial-character of the stresses produced

appear as a result of diffusion and reaction with the substance of the matrix. To ohdiiuch
maximum temperatures at.which the atablllzed~ atoms tire still able to exist, the studs of
paramagnetic resonance spectra must be carried out in a wide range of temperatures. The
