Abstract

The effects of solute-solvent interactions on vibrational spectra (IR) of dimethyldichlorosilane, in a number of solvents have been obtained. The spectral vibrational frequency shifts observed in different solvents have been correlated with refractive indices and dielectric constants of the solvents. The results obtained were applied to Buckingham's modification of the Bauer-Magat formula for solute-solvent interactions. Generally, IR spectral frequencies in solution phase shift to lower wavenumber than those observed in the gas phase. However, solution in chloroform resulted in a shift to higher wavenumber, which is due to specific interactions. The calibration lines between |ΔX/X| vs ε - 1 2ε + 1 were made to determine the specific and non-specific solute-solvent interactions. Results obtained from these calibration lines are also discussed in terms of solute-solvent interaction.
