Notes:
Raman spectra have been obtained for bleomycin A2 and selected fragments. Virtually all of the features in the bleomycin Raman spectrum can be attributed to the preresonance enhanced vibrational transitions of the 2,4′-bithiazole moiety as determined by comparison to the Raman spectra of bithiazole fragments. The Raman spectrum of bleomycin is dominated by a very intense band at 1542 cm-1 that can be approximately assigned as a bithiazole ring stretching mode. This feature may serve as a probe of bithiazole environment in bleomysin -DNA interactions.
