非康登激子光谱的相关振动-溶剂效应

Correlated vibration-solvent effects on the non-Condon exciton spectroscopy

Zi-Hao Chen, Yao Wang, Rui-Xue Xu, YiJing Yan

摘要:

激发能转移在许多体系中起着至关重要的作用。在此过程中,非Condon电子振动耦合和周围的溶剂相互作用可能协同发挥重要作用。本文研究了关联振动-溶剂效应对非康登激子光谱的影响。统计分析阐述了整体振动加溶剂的环境影响。推导了单体体系线性吸收的解析解。一般模拟准确地进行了通过耗散方程的运动方法。无论是在线性吸收或强场制度所产生的光谱清楚地表明,由于协同振动溶剂相关的相干增强。

英文摘要:

Excitation energy transfer is crucially involved in a variety of systems. During the process, the non-Condon vibronic coupling and the surrounding solvent interaction may synergetically play important roles. In this work, we study the correlated vibration-solvent influences on the non-Condon exciton spectroscopy. Statistical analysis is elaborated for the overall vibration-plus-solvent environmental effects. Analytic solutions are derived for the linear absorption of monomer systems. General simulations are accurately carried out via the dissipaton-equation-of-motion approach. The resulted spectra in either the linear absorption or strong field regime clearly demonstrate the coherence enhancement due to the synergetic vibration-solvent correlation.
