dc.description.abstractThe infrared and Raman spectra have been recorded for gaseous and solid ethyldimethylphosphine, $CH_{3}CH_{2}P(CH_{3})_{2}$. Additionally, the Raman spectra of the liquid has been recorded and qualitative depolarization values have been obtained. From the fact that several distinct Raman lines disappear on going from the fluid phases to the solid state, it is concluded that the molecule exists as a mixture of the gauche and trans conformers in the fluid phases with the gauche conformer being more stable and the only one present in the spectrum of the solid. A complete vibrational assignment is proposed for the gauche conformer, and is supported by a normal coordinate calculation which was carried out utilizing a modified valence force field to obtain the frequencies of the normal modes and the potential energy distribution. The asymmetric torsional mode has been observed for the gauche conformer in both the infrared and Raman spectra of the gas at $91 cm^{-1}$ with evidence of ``hot bands” at lower frequencies.en_US
