中文摘要: 本项目致力于发展一种新方法,用于理解光化学中的激发态现象。基于分子中原子的量子理论(QTAIM)框架,激发态现象的发展将同时使用QTAIM及基于量子压力张量的QTAIM分割。该方法将结合现有的其他理论方法,并且使用生成的总的电荷密度分布作为输入。该方法可用于解释多种光化学现象:光异构化、激发态分子内质子转移和圆锥形交叉。该工作基于我们原有的QTAIM研究基础,并引入新的基于量子压力张量的分割。上述方法的实施将成为探明一些分子为何在激发态发生反应的新理论工具。

英文摘要: The project is committed to the development of a new method for the elucidation of excited states phenomena for photo-chemistry. In the framework of the quantum theory of atoms-in-molecules (QTAIM) the proposed development of excited state phenomena will use both QTAIM and quantum stress tensor based atoms-in-molecules partitioning. This method will partner existing theory methods and will utilize their resultant total electronic charge density distributions as input. This method is suitable for many types of excited state phenomena; photo-isomerization, excited state intra-molecular proton transfer (ESIPT) and conical intersection seams. This can be achieved by applying my existing developments of QTAIM and realizing the potential of the new quantum stress tensor based partitioning. I hope that these two strands of the development of QTAIM can be implemented to become new tools for excited-state chemistry to determine why some molecules react on the excited state.
