Abstract
The superoxide anion, O2-, evolves singlet molecular oxygen in dimethylsulfoxide solution. Pronounced water quenching of superoxide-sensitized luminescence is indicative of the preferential generation of the 1σg+ state. Recent identification of O2- in the xanthine oxidase system suggests that the generation of singlet oxygen may also occur in enzymatic systems.Keywords
