ResumoThe infrared spectrum. (200–4000 cm−1) of phosphoryl chloride, deposited and annealed in a low temperature cell, was examined with 0.3–0.6 cm−1 resolution Spectra of the molecules isolated in argon, carbon dioxide and methane at liquid helium temperatures were also obtained. Raman shifts of crystals at −190°C were measured with a laser Raman spectrometer. Orientation effects observed by deposition on CsI windows are discussed. The density of the solid was determined near the freezing point. Analysis of the band splittings and polarization, complemented by packing considerations, leads to D162h as the most probable structure of crystalline POCl3.
