19F and31P magnetic shielding anisotropies in phosphoryl fluoride

Abstract
The 19F and 31P magnetic shielding anisotropies in the phosphoryl fluoride molecule have been determined from studies of the temperature dependence of the 19F and 31P chemical shifts and the anisotropic couplings in nematic solutions. Measurements of the F-P-F bond angle are reported. The possible existence of an anisotropy in the indirect P-F spin-spin coupling which is investigated does not change the values of the shielding anisotropies significantly.
