IR technique has been used to study the solute-solvent interaction of trimethylchlorosilane, methyltrichlorosilane and diphenyldichlorosilane in a number of solvents. The relative shifts in frequency, Δv/v, in different solvents have been correlated with refractive indices and dielectric constants of solvents. Generally, Si-Cl stretching vibrational frequency shifts towards lower wave numbers than those observed in the gas phase. Buckingham's modification of Bauer Magat formula was used to interpret the solute-solvent interactions. The calibration lines between Δv/v vs ε-1/2ε+1 were drawn. Results obtained from these calibration lines are also discussed in terms of solute-solvent interaction.
