Abstract

Ultraviolet resonance Raman (UVRR) spectra of H2O and D2O solutions of the nucleoside (dA, dG, dC, dT) and aromatic amino acid (Phe, Trp, Tyr) constituents of DNA viruses have been obtained with laser excitation wavelengths of 257, 244, 238, and 229 nm. Using the 981 cm(-1) marker of Na2SO4 as an internal standard, Raman frequencies and scatteringcross sections were evaluated for all prominent UVRR bands at each excitation wavelength. The results show that UVRR cross sections of boththe nucleosides and amino acids are strongly dependent on excitation wavelength and constitute sensitive and selective probes of the residues. The results provide a library of UVRR marker bands for structural analysis of DNA viruses and other nucleoprotein assemblies. (C) 1998 John Wiley & Sons, Inc.
