nevertheless t h e y are extractable by o t h e r organic s o l v e n t s such as hexane or petrol ether that are commonly used to o b t a i n e "sansa" olive oil from pomace, and seed oils as well. These considerations should make it plain that olive oil obtained by the simple physical procedures
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 quantum yield (F D ) of singlet oxygen (O 2 ( 1 D g ) production by 9H-fluoren-9-one (FLU) is very sensitive to the nature of the solvent (0.02 in a highly polar and protic solvent, such as MeOH, to 1.0 in apolar solvents). This high sensitivity has been used for probing the interaction of FLU w
