Theoretical and Experimental Chemistry Aims and scope

Abstract

A derivation is given for the formulas defining the operator for the spin-lattice interaction as averaged over the orbital motion of the unpaired electron in the solid. Simple formulas are derived for the constants of the spin-lattice interaction. It is shown that the relaxation time T1 of this interaction may be substantially dependent on the concentration of lattice defects at helium temperatures; approximate relations between T1 and the phonon mean free path are derived.
