RESUMEN

The geminate recombination of photodissociated carboxyhemoglobin (human adult) and its isolated subunits was studied by nanosecond laser photolysis. The rebinding kinetics were found not to depend upon the kind of buffer used or on pH but changed appreciably with the buffer concentration. The results are compared to oxygenation properties under the same conditions.
