Abstract

Abstract The infrared spectrá of methyl and silyl phosphines in the gas phase have been obtained over the region from 300 to 4000 cm −1 at prism resolution. A number of vibrational assignments have been made on the basis of a C s model, although in several instances overlapping of bands permits only approximate values for some band centers. The complex absorption from 400 to 500 cm −1 in SiH 3PH 2 suggests the possibility that the overtone of the internal torsion may lie in this region.
