Abstract

The low‐wavenumber (10–200 cm^−1^) polarized Raman spectra of 4,4′‐dibromobenzophenone single crystal at different temperatures (10–295 K) and far‐infrared spectra (20–200 cm^−1^) of powdered samples at room temperature were recorded. The assignment of the lattice vibrations based on the lattice dynamics calculation at k = 0, which takes into account the seven lowest intramolecular modes, is presented. The unusual temperature behavior of some bands was explained by dephasing relaxation processes. Copyright © 2002 John Wiley & Sons, Ltd.

## Abstract L‐Alanine is one of the simplest amino acids, the building block for many polypeptides and proteins. A previous Raman scattering study showed an anomalous temperature dependence of the intensity of the two lowest Raman modes, attributed to dynamic localization of vibrational energy. The

## Abstract The polarized Raman spectra in different environments along with the IR counterpart of 4‐benzoylpyridine (4‐BOP) were critically analyzed to assign all of its normal modes of vibration. The knowledge of the positions of different excited electronic states (EESs)was obtained from the stu
