Electronic Relaxation and Oxygen Recombination Processes in Photodissociated Oxyhemoglobin After Picosecond Flash Photolysis
Oxyhemoglobin photolysis has been investigated with picosecond laser techniques. Transient light absorption changes observed within 500–600 nm reveal two processes following photodissociation: electronic relaxation up to 400 ps after dissociation and a partial religation during 3 ns. The kinetics of oxygen geminate recombination at pH 7 and 22°C has a monoexponential decay with a lifetime of 1.5 ns ± 0.1 ns.
