We organized the 39th Symposium on Chemical Kinetics and Dynamics, which was held on Shizuoka City Culture Hall (Chairperson of the Committee was Prof. Shinnosuke Kawai). In this symposium, Mr. Oyaide (M2), Hayano (M2), and Furukawa (M2) gave poster presentations “Development of the optical cavity for observation of gas-phase vibrational polaritons”, “Study on hydrogen bonds of propargyl alcohol clusters by IR spectroscopy and quantum chemical calculations”, and “Development of the gas cell for observation of gas-phase vibrational polaritons”, respectively.
