Abstract

The modern theory of spin resonance and relaxation1,2 leads to a non-Markovian equation of motion for the spin density matrix. However, explicit expressions for the relaxation functions are always given in the short correlation time limit: it is assumed that the relevant time correlation functions decay on a much shorter time scale than the experimental one. It is well known that this Markovian approximation does not hold in many situations of interest, e. g. in supercooled liquids and solids at low temperatures.
