Abstract

The maxima positions of the Si-H stretching and bending absorption bands, at approximately 2100 and $810 cm^{-1}$, respectively, were determined within $\pm 0.3 cm^{-1}$ for a number of hydrosilanes in a wide variety of solvents. Solutes included triethylsilane, tricyclohexylsilane, triphenylsilane, tribenzylsilane, triethoxylsilane, and diphenylmethylsilane. Solvent-induced shifts are categorized into those involving generalized interactions and those due to specific molecular interactions with structural groups. Both ``well-behaved'' and ``poorly-behaved'' solvents are defined in terms of Bellamy plots and Allerhand-Schleyer G-values. Chemical explanations are given.
