International Symposium of JSPS Core-to-Core Program
International Symposium of JSPS Core-to-Core Program “Elucidation of Solvation Effect on Molecular Recognition” was held on July 29-30 at Tokyo Institute of Technology. Prof. Matsumoto had an opportunity of the oral presentation “Hydrated Structures of the charge-resonance pyrrole dimer cation by IR spectroscopy”.
39th Symposium on Chemical Kinetics and Dynamics
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.
Final lecture by Prof. Masaaki Fujii (Tokyo Tech.)
Research proposal is accepted
Our research proposal “Study on aromatic charge resonance complex probed by IR spectroscopy” has been accepted by the Network Joint Research Center for Materials and Devices. This study will collaborate with Prof. Shun-ichi Ishiuchi at Tokyo Institute of Technology. We will study IR spectroscopy of solvated clusters with pyrrole dimer cations to investigate the relationship between solvated structures and intra-cluster charge distribution.
Grant-in-aid for scientific research
Our research proposal, “Study on the state of vibrational strong coupling in gas-phase molecules by IR spectroscopy and cavity-QED theory“, has been adopted for Grant-in-Aid for Scientific Research (B).
Joint research with Prof. Otto Dopfer
Prof. Matsumoto visited the laboratory of Prof. Otto Dopfer at Technical University Berlin on March 18 – 25, 2024. This was the opportunity for our joint research supported by the JSPS Bilateral Exchange Program between Japan and Germany. We proceeded to write our manuscript on IR photodissociation spectroscopy of the hydrated clusters of pyrrole dimer cations (Py2+(H2O)n).
Research presentation by undergraduate students
Three undergraduate students in our laboratory, Mr. Eiyu Mitsukawa, Ms. Haruka Nishimura, and Mr. Shintaro Koakutsu, had a research presentation for the Department of Chemistry. Their talk titles are “Simulation study on controlling optical cavity for vibrational strong coupling”, “Structural analysis of 2,5-dimethylpyrrole – water clusters by IR spectroscopy”, and “Structural analysis of 2,5-dimethylpyrrole – propylene oxide clusters by IR spectroscopy” by EM, HN, and SK, respectively.
Defense of master thesis
Ms. Yukino Yamada (M2) had the defense of her master’s thesis on February 14. The title of her thesis is “Structural analysis of pyrrole – tetrahydrofuran solvated clusters probed by IR cavity ringdown spectroscopy”.
Paper Published
The paper “Visualization of the sequence of changes in full wavenumber range by two-dimensional correlation spectroscopy” was published in Chemical Physics Letters. We contributed our IR spectra of the gas-phase pyrrole clusters for this study.
