[Study of nucleoside phosphorescence with a phosphorescent microscope].
Phosphorescence of ribonucleosides and desoxyribonucleosides is studied. The phosphorescence spectra of polycrystalline powders of adenosine, guanosine, thymidine, uridine, cytidine, desoxyadenosine, desoxyguanosine and desoxycytidine are recorded at -175 degrees C as well as the decay curves at -175 degrees C. The phosphorescence spectrum of guanosine is also recorded at room temperature. The decay times of phosphorescence of adenosine and cytidine are determined at room temperature too. Obtained values of pi for nucleosides are shorter than those for nucleic acid bases.
