Abstract
Synchronous room-temperature phosphorescence (SRTP) spectra of synthet ic binary mixtures of purines and pyrimidines have been determined on Whatman No. 40 filter paper in the presence of heavy ions (I- or Tl+). The SRTP spectra were characterized by well-resolved peaks that could be used for identification of individual compounds. SRTP gave satisfa ctory results for the analysis of pharmaceutical formulations. No sign ificant interference of the excipient or of an added phosphorescent fo reign species was found. The mean recoveries ranged from 80 to 106%.
