Vibrational mode analysis of guanine by neutron inelastic scattering.
The low-temperature neutron inelastic spectrum of guanine has been measured. In order to assign the intense peaks observed in this spectrum, a normal mode analysis has been performed, using the Wilson GF-method. The theoretical treatment is based on a non-redundant set of internal coordinates, and a simplified valence force-field approximation. Only the fundamentals have been considered for simulating the internal vibrational mode spectrum. The calculations account for the spectral shape as well as the main observed peaks.
