## Abstract The characteristic time of exciton relaxation due to phonons is estimated, and as it turns to be smaller than the exciton lifetime, it is concluded that Bose‐Einstein condensation is possible in the system of Frenkel excitons. It is further shown that kinematical interaction obtained in
