Studies that elucidate the behavior of the hemoglobins (Hbs) and myoglobins upon reaction with hydrogen peroxide are essential to the development of oxygen carrier substitutes. Stopped-flow kinetics and resonance Raman data show that the reaction between hydrogen peroxide and oxygenated and deoxygen
