Energy transfer in the quenching of singlet molecular oxygen - I. Kinetics of quenching of singlet oxygen

Quenching studies have been made in a spherical vessel containing known concentrations of O2(1∆g) and O2(1∑+g). Rate coefficients for the quenching of O2(1∆ ) by CO and of O2(1∑) by N2O, D2O, NH3, C3H8, C2H2, HCl and DCl have been determined. Efficient wall deactivation of O2(1∆) by adsorbed hydrogen halides was observed.
