The Stochastic Basis of Spin Relaxation

Abstract

The characteristics of molecular dynamics are reflected by the analytical form of the correlation function or spectral density of the fluctuating spin interactions. As a simple illustrative example, isotropic rotational diffusion of molecules is treated. The rules for establishing correlation functions for single or multicomponent molecular dynamics are discussed. This includes the often encountered experimental detection problem of a slow fluctuation component superimposed on fast restricted reorientations.
