  1. Sensing the Molecular Properties in Methanol and Its Binary Mixtures Using Time-Resolved Thermal Lens Spectrometer. S. Chakraborty, A. K. Rawat, and D. Goswami, in 2019 Workshop on Recent Advances in Photonics (WRAP) (2019), pp. 1–3 [Abstract] [BibTeX]

    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 (CCl4) at different concentrations of methanol is investigated. Methanol has the highest Thermal Lens (TL) signal, and CCl4 does not have any TL signal at all. However, the presence of CCl4 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.

  2. Thermal Inflection Study of Methanol-Hexane Mixtures Using Time-Resolved Thermal Lens Technique. A. K. Rawat, S. Chakraborty, and D. Goswami, in 2019 Workshop on Recent Advances in Photonics (WRAP) (2019), pp. 1–3 [Abstract] [BibTeX]

    Abstract: Time-resolved thermal lens (TL) technique is used to measure the heat transfer in pure methanol and its binary mixtures with hexane. We used dual-beam mode mismatched pump-probe scheme where a femtosecond laser beam of 1560 nm was used as a pump beam, and its frequency-doubled 780 nm beam was used as probe beam. TL Signal decreases with increasing concentration of hexane in the binary mixture. On higher concentration of Hexane in binary mixture then we have found convective heat transfer mode was absent. At 40%-60% methanol hexane mixture, we observed a sudden curious jump in TL signal.
