Abstract
The nonexponential recombination of photodissociated heme‐CO and heme‐O2 in myoglobin, which is geminate at T < 180 K, is interpreted as being due to a narrow, random distribution of ligand transfer distances in the heme pocket. This permits evaluation of the most probable recombination rate which is shown to be consistent with ligand tunneling.Keywords
