Fujii 교수의 연구실은 분자 집합체와 고체 상태에서의 분자 구조 및 동역학을 초고해상도 분광법을 통해 연구합니다. 주로 전자기파를 이용한 분광 기법(예: UV-UV-IR, IR-UV 탈구광법)을 활용해, 수소결합, π-결합, 이온화 유도 반응 등에서의 이성질체적 구조 전환과 동적 거동을 규명합니다. 특히 페놀 유도체 및 아미드 유사 분자의 이성질체적 성질과 그 상호작용을 중심으로 기초 분자 과학적 이해를 심화하고 있습니다.

The ionisation-induced π → H site switching reaction in clusters of phenol solvated by rare gas ligands, PhOH–Rg n (Rg = Ar and Kr, n = 1–3), is characterised by electron impact infrared (EI–IR) photodissociation as well as nanosecond and picosecond time-resolved UV–UV–IR spectroscopy. The EI–IR spectra of the PhOH+–Rg dimers demonstrate that the H-bound isomer is the most stable structure in the ground electronic state of the cation, in which the Rg atom forms a hydrogen bond to the OH group of
We measured the infrared (IR) spectra of supersonically cooled N-phenylformamide (formanilide) and N-phenylacetamide (acetanilide) in the amide band and X-H stretch vibration regions by using IR-UV depletion spectroscopy combined with a newly developed mid-IR light source based on difference frequency generation in ZnGeP(2). The two rotational isomers, cis- and trans- of the amide group were separately monitored to record the IR spectra. Both of the conformers showed similar features in the amid
