title: Phosphorus-31 MAS NMR investigations of pyridine stabilized dithiomonometaphosphoryl halides.
abstract: Phosphorus-31 magic-angle spinning NMR spectroscopy was chosen in order to study a series of N-donor stabilized dithiomonometaphosphoryl halides (F, Cl, and Br) and to extract structural and bonding information from their spectra. Additionally, an unusual line splitting was observed in the 31P MAS NMR spectra of pyridine dithiomonometaphosphoryl chloride (Py-->PS2Cl) and the analogous bromide (Py-->PS2Br). It is shown that this effect is due to a residual dipolar coupling between phosphorus and chlorine or bromine, respectively. This work is to our knowledge the first observation of this effect between P and Br in 31P MAS NMR spectra.
