We have derived a line-shape function [J. Chem. Phys. 124, 074304 (2006); Proc. Sch. Sci, Tokai Univ. 41, 83 (2006)] for the spontaneous emission from an electronically excited molecule in a solvent on the basis of following assumptions: (i) The initial state of an excited molecule is thermalized; (ii) the interaction between the excited molecule and a solvent can be disregarded during the time evolution of the system under consideration. In this paper, excluding the latter assumption (ii), we develop the time evolution of an excited molecule in a solvent using a reduced density operator, and derive a basic equation for calculating a transition rate. As an example, we show that its basic equation leads to a line-shape function on the assumptions (i) and (ii) in the weak limiting case of the interaction between an excited molecule and a solvent.
