Abstract
The EPR detection of nitroxide formation and the observation by thin layer chromatography of the specific1O2 oxidation product of cholesterol, have been used to appreciate singlet oxygen production by promazine and four of its derivatives during irradiation with near-UV light of ethanolic and aqueous solutions. Within the range of sensitivity of the methods, no1O2 has been detected.Keywords
