我们提出了受半经典浴影响的分子系统中激子与电荷转移态相互作用的系统密度矩阵理论。研究了激子二聚体与过阻尼布朗振子浴的非线性相互作用，并证明了与浴相互作用的本征态重正化效应在正确描述激子-电荷转移态系统的吸收光谱的异常温度依赖性中是必不可少的。(c)2006年由Elsevier B. V.出版
We present a systematic density matrix theory of excitons interacting with charge transfer states in molecular systems subject to influence of a semiclassical bath. An excitonic dimer interacting non-linearly with an overdamped Brownian oscillator bath is studied, and the effect of eigenstate renormalization by interaction with the bath is shown to be essential in a correct description of the unusual temperature dependence of the absorption spectrum of the exciton-charge transfer state system.
