实验物理化学计划支持理查德法官 威斯康星大学帕克赛德分校继续他的高分辨率 硅中单重态-三重态跃迁的光谱研究 二氟化物、二氧化硒、亚甲基硒和乙醛。 在 在前三种情况下，他将把早期的工作扩展到更高的水平， 分辨率或更高的振动水平。 在后一种情况下，他将 研究激发三重态的内旋转。 对光谱的分析将产生关于 几何学和激发态分子动力学。 这些信息将 极大地有助于解释观察到的光化学反应。 在 特别是，在分析中发现的扰动 单重态-三重态光谱将产生关于处置的有价值的信息。 在电子促销活动中获得的多余能量。 本科生 将直接参与研究，无论是在分析期间， 数据采集

The Experimental Physical Chemistry Program supports Richard Judge of the University of Wisconsin-Parkside to continue his high resolution spectroscopic studies of singlet-triplet transitions in silicon difluoride, selenium dioxide, methylene selenide and acetaldehyde. In the first three cases, he will extend earlier work to either higher resolution or higher vibrational levels. In the latter case, he will investigate internal rotation in the excited triplet state. Analysis of the spectra will yield accurate information about the geometry and excited state molecular dynamics. This information will greatly assist in the interpretation of the observed photochemistry. In particular, perturbations uncovered in the analysis of the singlet-triplet spectra will yield valuable information on the disposal of excess energy gained on electronic promotion. Undergraduate students will directly participate in the research either during the analysis or data acquisition.
