    A theoretical model is studied of the coupling of several electronic states to a vibrational manifold. In this approach, the vibrational manifold is divided into two subbaths. The first one, a coherent subbath, interacts coherently with electronic states. The second one, a thermalizing subbath, is responsible for relaxation of vibronic energy. In the first step, the thermalizing subbath is projected out, under the assumption of a standard (Markovian) approximation in the interaction picture and the effective dissipative Liouville equation for a coherent vibronic system (electronic states + coherent bath modes) is thus obtained.
