Abstract
The infrared spectra of ethylmethylsilane, CH3CH2SiH2CH3, its deuterated species, CH3CH2SiD2CH3, and a mixture of CH3CH2SiHDCH3, CH3CH2SiH2CH3, and CH3CH2SiD2CH3 have been measured in the gaseous, liquid, and crystalline states. The Raman spectrum of ethylmethylsilane has also been measured in the liquid state. Vibrational assignments have been made in relation to the rotational isomerism, on the basis of a modified Urey-Bradley force field, in which the force constants have been transferred from those for dimethylsilane and ethylsilane. The conclusion regarding the molecular forms of the rotational isomers, which has been obtained from the experimental evidence of the SiHD deformation vibrations for an asymmetrically-deuterated species, CH3CH2SiHDCH3, can be considered to be also supported by the present results of the normal vibration calculations.
