A general theory is given accounting for the secondary radiation which is excited in condensed matter exposed by light at finite temperatures, T ≧ ħω s , where ω s is the radiation frequency. The formula which is derived for a light scattering tensor of rank four, is similar to that obtained by Kubo for the conductivity tensor. It allows for all types of interactions possible within the scattering medium. The obtained results are compared to conclusions in the cases of either low, T ≪ ħω s , or T ≥ ħω s temperatures.
