We had the 16th Annual Meeting of Japan Society for Molecular Science on 19-22 September at Keio University (Yokohama). Ms. Arisu Hirota (M2) and Mr. Yusuke Ishihara (M2) have provided their oral and poster presentations, in which their titles are “Dual dihydrogen-bond formations of jet-cooled acetylene-alkylsilane clusters studied by IR spectroscopy” and “Study on 13C6H6 large clusters by IR spectroscopy”, respectively. Prof. Matsumoto has also presented an oral talk about “Charge resonance interactions in pyrrole dimer cations and its hydrated clusters probed by IR spectroscopy”.
