项目摘要
Professor Lim is supported by a grant from the Experimental Physical Chemistry Program to study the structure and spectra of van der Waals dimers, excimers, and bicimers (doubly excited) of aromatic hydrocarbons for the purpose of deducing the dependence of the structure on the nature of the electronic state. Experimental techniques will include time- and energy-resolved spectra in absorption and/or emission. A comparison of these intermolecular dimers with the corresponding diaryl alkanes which are their intramolecular dimer counterparts will provide spectral and temporal characteristics from which can be deduced structural features and energetics of vibronic transitions for the three classes of molecular dimers. Theoretical studies of the two interacting molecules as a function of their relative orientation will be combined with the experimental studies for a detailed characterization of these species. %%% The combination of experimental and theoretical approaches is expected to lead to an understanding of the dependence of the structure of the dimers on the nature of the electronic state of the hydrocarbon and contribute to our understanding of energy flow in these systems and the intermolecular forces that hold the pair of molecules together.
林教授得到了实验物理化学计划的资助,研究芳香烃的范德华二聚体、准分子和双异构体(双激发)的结构和光谱,目的是推断结构与电子态性质的关系。实验技术将包括吸收和/或发射中的时间和能量分辨光谱。将这些分子间二聚体与相应的分子内二聚体二芳基烷烃进行比较,可以提供光谱和时间特征,由此可以推断这三类分子二聚体的结构特征和振动跃迁的能量学。两个相互作用的分子作为其相对取向的函数的理论研究将与实验研究相结合,以详细描述这些物种的特征。实验方法和理论方法的结合有望有助于理解二聚体结构对烃类电子态性质的依赖关系,并有助于我们理解能量流动在这些系统中,以及将这对分子结合在一起的分子间力。
