Abstract
The infrared and Raman spectra of 3-butenylsilane, CH2=CHCH2CH2SiH3 (and –SiD3), were measured for the gaseous, liquid, and solid states. The fundamental vibrations were assigned, and the normal vibrations were calculated in relation to the rotational isomerism. The calculations indicated that the cis-trans (CT), skew-trans (ST), and skew-gauche (SG and SG′) forms coexist in the gaseous and liquid states, while the CT form only persists in the solid state. From the temperature variation in the Raman intensities, the stability of the molecular conformations was found to be in this order: CT\gtrsimST>SG′>SG in the liquid state, indicating that an appreciable interaction between the silicon atom and the C=C bond, such as in the case of allylsilane, is not present for 3-butenylsilane.
