The second CH stretch overtone of benzene has been studied both experimentally and theoretically. A recent high-resolution opto-thermal experiment showed that the overtone spectrum consists of several absorption bands located in the region between 8730 and 8875 cm-'. In this work, we investigate pos

โฆ Synopsis
A simple dynamical model is used to calculate the overtone spectra of CH and CD stretch vibrations of C6H6 and C6D6 in both vapour and liquid phases. The quantized version of this model describes the normal-mode character of the first excited states. A semiclassical version describes the local-mode character of the overtone bands.

The Raman scattering of two vibrational overtones of benzene is found to undergo strong preresonance enhancement as the excitation frequency approaches the state, the lowest lying, forbidden electronic transition at 265 am. These preresonance active modes are the first overtone of the 606 cm-l eZS f
