The energy relaxation of rf acoustic phonons in thin anthracene crystals has been studied experimentally. A comparison with the results of model-based calculations has made it possible to estimate the parameters of the distribution of acoustic phonons generated during the relaxation of the electronic excitation and also the lifetime of the acoustic phonons relative to the anharmonic processes.
