Chemical Shift and Relaxation ofXe129in Xenon Gas

Abstract

The density-proportional chemical shift observed by Carr and his associates in xenon gas can be used as a means of calibrating the spin-rotational coupling existing in a diatomic xenon system during collisions of xenon atoms. The basis of this calculation is Ramsey's theory of chemical shifts. The value of the coupling thus obtained is of the correct magnitude to account for the observed relaxation of ${\mathrm{Xe}}^{129}$ in xenon gas.
