The research presentation in the Department of Chemistry was held on Feb. 27-28. Four students in our laboratory, Mr. Miyashita, Ms. Hara, Mr. Hayashi, and Mr. Fukui, gave their presentations of “Cavity transmission for polaritonic chemistry”, “Chirality recognition of molecular dimer”, “IR spectroscopy of dihydrogen-bonded clusters”, and “Dependence of dihydrogen bond strength on its angle”, respectively. We were pleased to enjoy nice presentations.
