中文摘要
实验物理化学项目支持Pratt教授的研究小组继续研究大型有机分子的高分辨率电子光谱。从这些研究中获得的信息导致了重大的定量测试和显著的定性改进,我们对大分子分子间能量流动的理解。在研究的激发能为3-4 eV,光谱分辨率为几MHz时,激发态的离散自旋-旋转-振动能级嵌入到属于一个或多个低电子态能级的高密度流形(甚至准连续体)中。这些流形之间的耦合允许快速发生有趣的化学过程;本研究试图从特征态解析谱中提取这些耦合的信息。
英文摘要
The Experimental Physical Chemistry Program supports the research group of Professor Pratt in a continued investigation of high-resolution electronic spectroscopy of large organic molecules. The information gained from these investigations is leading to significant quantitative tests and dramatic qualitative improvements in our understanding of intermolecular energy flow in large molecules. At the studied excitation energies of 3-4 eV and the spectroscopic resolution of a few MHz, the discrete spin-rotation-vibration energy levels of excited electronic states are imbedded in a higher density manifold (or even a quasi-continuum) of levels belonging to one or more lower electronic states. Couplings between these manifolds permit rapid occurrence of chemically interesting processes; the research attempts to extract information about these couplings from eigenstate-resolved spectra.
