U.S.-Japan Cooperative Research: Photoconversion/Photo- synthesis Spectroscopic and Dynamical Studies of the S1 and S2 States of Models Polyenes in Supersonic Molecular Beams

该奖项将支持由缅因州不伦瑞克鲍登学院化学系Ronald Christensen教授和日本冈崎分子科学研究所电子结构系Keitaro Yoshihara教授共同开展的为期两年的美日合作光转换/光合作用研究项目。此次合作将重点研究简单四烯和三烯在超音速分子束中的S1和S2激发态的光谱和动力学。目的是获得更详细的了解光型多烯体系的光异构化。这个研究多烯电子光谱的项目涉及具有互补技能和设备的科学家之间的合作实验。他们使用荧光和荧光激发技术的研究有望对正在进行的研究做出重大贡献，并将补充其他基于多光子电离的方法。克里斯滕森教授将前往冈崎提纯他的化合物，并将参与光谱实验的指导和解释。

This award will support a two-year U.S.-Japan Cooperative Photoconversion/Photosynthesis Research Program project between Professor Ronald Christensen, Department of Chemistry, Bowdoin College, Brunswick, Maine, and Professor Keitaro Yoshihara, Department of Electronic Structure, Institute for Molecular Science, Okazaki, Japan. The collaboration will focus on the spectroscopy and dynamics of the S1 and S2 excited states of simple tetraenes and trienes in supersonic molecular beams. The goal is to obtain a more detailed understanding of photoisomerization in phototypical polyene systems. This project to study the electronic spectra of polyenes involves cooperative experiments between scientists with complementary skills and facilities. Their studies using fluorescence and fluorescence excitation techniques promise to make substantial contributions to ongoing research and will complement other methods based on multiphoton ionization. Professor Christensen will travel to Okazaki to purify his compounds there and will participate in the conduct and interpretation of the spectroscopic experiments.
