项目摘要
Central part of the proposed research project is the elucidation of the physical nature of S1->Sx excited state absorptions (ESA) of monomer molecular systems which appear in the spectral region of the most long wavelength band of the absorption spectrum. Goal of the project will be to decide if in singlet systems only one of the two valence electrons leaves its ground state orbital or both electrons do. Despite the fundamental importance of this problem to my knowledge there is neither a theoretical nor an experimental answer, yet.The exact acquaintance of excited state absorptions of molecules is increasingly desirable because they often disturb applications in optical systems. Otherwise, excited state absorptions can also open new fields of application.To clarify the above mentioned physical background of these excited state absorptions in detail the requested project deals with a quantitative analysis of monomeric molecular systems with two valence electrons (singlet systems). The investigations will be supplemented by comparing them with molecular systems having only one valence electron (doublet, triplet systems).
拟议研究项目的核心部分是阐明出现在吸收光谱最长波长带的光谱区域中的单体分子系统的 S1->Sx 激发态吸收 (ESA) 的物理性质。该项目的目标是确定在单线态系统中,是否只有两个价电子之一离开其基态轨道,还是两个电子都离开其基态轨道。尽管据我所知,这个问题非常重要,但目前还没有理论或实验的答案。人们越来越需要准确了解分子的激发态吸收,因为它们经常干扰光学系统中的应用。另外,激发态吸收也可以开辟新的应用领域。为了详细阐明这些激发态吸收的上述物理背景,所请求的项目涉及具有两个价电子的单体分子系统(单线态系统)的定量分析。通过将它们与仅具有一个价电子的分子系统(双线态、三线态系统)进行比较来补充研究。
