Time-Resolved Spectroscopy of Hemoglobin and Its Complexes with Subpicosecond Optical Pulsess

Abstract

Subpicosecond optical pulses have been used to study the photolysis of hemoglobin conplexes. Photodissociation of carboxyhemoglobin is found to occur in less than 0.5 picosecond. In hemoglobin and oxyhemoglobin a nondissociative excited state recovery in 2.5 picoseconds is observed.
