The1H and31P N.M.R. spectra of phosphine in isotropic and nematic solvents

Abstract
The proton and 31P N.M.R. spectra of PH3 in various isotropic and liquid crystal solvents are discussed. Geometrical data and chemical shielding anisotropies for 1H and 31P are reported. The temperature dependence of the isotropic chemical shift and its influence on the evaluation of measurements in nematic solvents is discussed.
