It was possible to measure the phosphorescence of singlet oxygen ('0,) sensitized by tctraphenylporphinc (TPP) by means of a sensitive pyroelectric radiometer. The IO2 phosphorescence quantum yield was determined directly by comparison of the intensities of the spectrally unresolved emissions of '02

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
