title: [Mechanism of photooxidation of porphyrins with oxygen].
abstract: Dependence of quantum yield of porphyrines photooxidation with oxygen on their concentration has been shown. Sensitized by some porphyrines oxidation of other ones with oxygen has been studied in relation to concentration, intensity and wave length of absorbed light, quantum yield, interconversion and life time of the molecules in triplet state. Common mechanism for direct and sensitized photooxidation has been suggested.
