Notizen: The Fluorine-19 NMR Spectrum of Methylthiotetrafluorophosphorane
2014
Johannesen, Rolf B. | Peake, S. C. | Schmutzler, R.
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.
