SOLVENT EFFECT ON SI-H STRETCHING BANDS OF SUBSTITUTED SILANES

Infrared frequencies of Si-H stretching vibration bands of dimethyl na phthoxy silane and dimethyl quinoxy silane have been measured in a num ber of solvents. The results have been used to examine the importance of the bulk dielectric effect and specific solute-solvent interactions . The deviation from the Kirkwood-Bauer-Magat relationship produced by polar, as well as by non-polar, solvents is analysed in terms of the formation of molecular complexes.
