Electronic coherence effects on population transfer by intense ultrashort chirped pulses in molecules coupled with a dissipative environment

Summary form only given. The effect of relaxation processes on a coherent excitation of a molecule coupled with a dissipative environment is an intriguing question. The purpose of this work is to answer the following question: How does dissipative environment influence on a coherent excitation of a molecule? We have studied the influence of the chirp rate on the excited state population after the completion of pulse action. We used a model of Gaussian-Markovian modulation for description of relaxation processes.
