Abstract

Mode Mismatched Pump-Probe spectroscopic method was employed to examine the thermally induced nonlinear optical properties of methanol and its binary mixtures. The heat transfer mechanism in methanol and its binary mixtures with carbon tetrachloride (CCl 4 ) at different concentrations of methanol is investigated. Methanol has the highest Thermal Lens (TL) signal, and CCl 4 does not have any TL signal at all. However, the presence of CCl 4 modulates the TL signal of the binary mixture. The time-domain shift in TL signal is observed for different concentrations of methanol, which indicates the unusual molecular behavior in the binary mixture.
