Theoretical Description of Spin-Lattice Relaxation,y, the lattice vibrations only influenced a spin through the modulation of the spin-spin interaction. The predicted variations of . . with temperature were of the form later observed experimentally, but Waller’s calculated values of . . were several orders of magnitude greater than those measured later by Gorter.

CLIFF

Cross Relaxation,e spin . = ? for the magnetic ions. In the present chapter we shall not consider the general case of . > ?; we postulate instead the presence of more than two spin levels, but we require a simple relation between the splittings of at least two pairs of the levels, in order that . can occur.

In the case of the direct process in Kramers salts it was necessary to invoke the presence of higher energy levels, but their effect was confined to the mixing of some small parts of their wave functions, through the application of the steady magnetic field. Thus we had assumed an effectiv

Diabetes mellitus and atherosclerosisearly work is given by Gorter in his book. and a later summary is given by Cooke.. In much of this work the measurements consist either of dispersion or of absorption measurements at audio frequencies and the relaxation time is deduced from an analysis of the data in a manner which will be described

R. Tsujimura,N. Kariyama,N. Hatotaniot in general be simply related to the spin-lattice relaxation time T. defined in Chapter I; it is more likely instead to be a weighted mean of the relaxation rates of all populated paramagnetic states. With the advent of spin resonance techniques, however, it became possible to measure the actual p
