摘要

From the critical analyses of Raman and infrared spectra, different normal modes of vibration of diphenylmethane (DPM) have been identified. The near ultraviolet absorption spectra of the molecule are found to consist of two band systems, one around 220 nm and the other around 270 nm with respective f-values 5.23 x 10(-2) and 6.44 x 10(-3). The first system is broad and shows few diffuse structures, whereas the later one exhibits very well-resolved structure. They are respectively assigned as L-1(a) and L-1(b) bands. The Raman excitation profiles of several normal modes have been analyzed to get structural and other information of different excited electronic states. (C) 2004 Elsevier B.V. All rights reserved.
