The absolute quantum yields, QAd, of photosensitized formation of singlet molecular oxygen, O2 (I$), by various sensitizers in benzene were measured by time-resolved thermal lensing (TRTL). Relative measurements with time-resolved O,( 'Ag) phosphorescence detection were used to confirm the absolute
