Calculation of dipolar correlation function in solids with internal mobility

Solid State Nucl Magn Reson. 2004 Jan;25(1-3):15-20. doi: 10.1016/j.ssnmr.2003.03.022.

Abstract

A general equation for the dipolar correlation function, to be used to analyze various kinds of independent internal motions, described by some correlation times tau(cm) (m = 1,2 em...k), has been obtained. The obtained expression has been used to analyze the temperature dependencies of different NMR measured values: second moment: spin-lattice relaxation times; amplitude of solid echoes signals.
