• The fully quantum-mechanical description of the transient resonance Raman scattering including the light source and the observation process is presented, which satisfies automatically the uncertainty relations between the energy of an absorbed or emitted photon and the time of the absorption or emission event, and further which involves all the possible effects of the radiation-matter interaction; the longitudinal and transverse radiative dampings in the intermediate state, the formation of exciton-polariton and the skin effect in opaque medium. The correct definition of the time-resolved emission spectrum is given, by introducing the "coherence time" of the spectrometer Δt_c and the time interval Δt over which the average counting rate is taken. It is shown that only the photons emitted during [t-Δt_c, t] can be observed by the photon counter at time t. Radiative damping in the intermediate state is investigated in detail without specifying the system and the conditions on which the momentarily Ansatz for radiative transition is justified are found to be looser than those appraised by Toyozawa.
