Abstract
Competitive behavior of two channels of resonant Raman scattering and luminescence is theoretically discussed for giant two-photon excitation of excitonic molecule. Time-integrated and time-resolved emission spectra of the excitonic molecule excited resonantly by a short pulse are described in terms of the stochastic theory of intermediate state interaction. Particularly we propose the time-resolved spectrum in which the frequency-time uncertainty due to the finite observation time is incorporate. This theory is shown to explain the observed characteristics of the emission spectra, and the relaxation constants of the excitonic molecule in the intermediate state and the exciton in the final state are determined from comparison between the observed and the calculated spectra.
