✦ Synopsis

The title compound has been synthesised, and characterised by multinuclear magnetic resonance spectroscopy, both in solution and in the solid state. The bandshapes of variabletemperature solution-state 19 F NMR spectra have been iteratively fitted to obtain information on the kinetics of rotation about the PC bond for one of the aryl groups, and values for the enthalpy and entropy of activation of the process have been derived. Magic-angle spinning NMR techniques have been extensively applied to the solid, using 19 F, 31 P and 13 C nuclei. Triple-channel methods and different magnetic field strengths have been employed to yield a range of complementary information. Heteronuclear interactions and intram-
