Notes:
The frequencies observed for adenine in the Raman spectra of adenosine monophosphate (AMP) and biopolymers such as poly(A), DNA, and RNA are compared with those calculated for a model compound, 9-methyladenine, in which the methyl group is taken as a unit mass concentrated on the carbon. The force field used is a Urey-Bradley field already tested on polycrystalline adenine and its analogs D-substituted on the nitrogens, on the carbon at position 8, and on both. Assignments for adenine residue Raman bands are proposed and discussed on the basis of observed and calculated D-shifts. These assignments are examined, in particular, for bands common to both adenine and guanine residues by analysis of their behavior for Raman hypochromism.
