摘要：

A microscopic model for relaxation in the course of CO rebinding to heme proteins has been developed. The model demonstrates that above 170 K the barrier height for the ligand-heme geminate recombination increases with time non-exponentially and that the relaxation rate coefficient does not obey the Arrhenius law. These and some other theoretical findings are shown to be in agreement with recent results of flash photolysis experiments on carbon monoxymyoglobin.
