Abstract
The low-temperature 19F NMR spectrum of the stereochemically non-rigid compound, CH3SPF4, shows three fluorine environments, one for the equatorial and two for the nonequivalent axial fluorine atoms. Each of the twelve lines of the upfield 19F- (axial) resonance shows further fine structure, due to coupling between 19F and the protons of the CH3S group. The center peaks of the two multiplet components reveal apparent quintet structure which, based on a computer simulation of the 19F spectrum of CH3SPF4, is rationalized in terms of accidental overlap of two quartets.Keywords
