The overall objectives of the present work are to investigate mechanisms of chemical reactions which give rise to electronically excited molecular oxygen and to determine factors responsible for its deactivation in solution, thereby providing the means for optimization of gaseous singlet oxygen formation by homogeneous reaction. Studies have focused upon hypochlorite oxidation of hydrogen peroxide, this reaction having been shown to yield substantial amounts of singlet molecular oxygen . Inasmuch as the redox kinetics were not well-characterized, we have undertaken a thorough analysis of the rate behavior and reaction stoichiometry. Where tractable, measurement of singlet oxygen yields by the various reaction pathways has been made using chemical trapping agents selective for singlet oxygen.Author
