Motional narrowing of Zeeman resonance lineshapes. II. Monte Carlo simulation results

For pt.I see ibid., vol.10, no.5, p.931 (1977). A simple model applicable to a class of high-resolution Zeeman spectroscopy experiments is simulated using Monte Carlo techniques. For individual Legendre polynomial field gradients, h approximately rnPnwith n=1-4, the authors find the autocorrelation function (h( tau )h(t+ tau )), correlation time, relaxation function and lineshape for a range of the narrowing parameter 0.1<< Delta tauc<<10.0. The bounds placed on the correlation time,mintaun c 1, prove to be useful in estimating the width and frequency shift in arbitrary field gradients.
