The authors would like to express deep gratitude to A. M. Glukhoi for recording the mass spectra of the BFA. LITERATURE CITED i. V. A. Basyuk, Teor. Eksp. Khim., 26, No. i, 97-102 (1990). 2. V. A.

SELECTIVE ANALYSIS OF NUCLEIC ACIDS IN MYCOBACTERIA ACCORDING TO RAMAN RESONANCE SPECTROSCOPY DATA A. V. Feofanov, V. I. Okolelov, A. P. Tatarinov, E. S. Martynova, R. G. Efremov, I. R. Nabiev, V. Z.

Manykin UDC 577.152 The appearance of reliable sources of monochromatic radiation in the 190-300 nm range has stimulated active development of Raman resonancespectroscopy with excitation in the UV region (UV RR) as applied to investigations of the structure and properties of biological molecules - nucleic acids, proteins, and their components [1-8]. Systematization and analy- sis of the experimental data have made it possible to begin investigations of supramolecular complexes and whole microorganisms [9-14]. The theoretical possibility of obtaining UV RR spectra of cells in a wide excitation wavelength range has been demonstrated in a number of studies [10-14]. One of the main advantages of the method under consideration is the possibility of selective excitation of the Raman resonance spectra of protein groups, nucleo- tide bases [11-13], as well as other types of chromophores [14] in the cells. Such an ap- proach permits simplification of the study of biological objects with a complex composition. M. M. Shemyakin Institute of Bioorganic Chemistry, Academy of Sciences of the USSR, Moscow.
