  • Title: Indirect EPR evidence for the production of singlet oxygen in the photosensitization of nucleic acid constituents by proflavine.
    Author: van de Vorst A, Lion Y.
    Journal: Z Naturforsch C Biosci; 1976; 31(3-4):203-4. PubMed ID: 183404.
    Abstract:
    EPR spectroscopy is used to analyse the influence of D2O and NaN3 on the free radicals induced in frozen aqueous solutions of 5'-thymidine monophosphate photosensitized (lambda greater than 320 nm) by proflavine at 205 K. The results can be explained if the production of singlet oxygen during the process is assumed.
