✦ Synopsis

Tunable UV lasers were used to study the resonant Raman effect near the origin of the 3200 A band of crystalline naphthalene at low temperatures. It was found that with the excitation frequency off tuned by about 20 cm-' beLow the O-O of Sr , the Raman spectra are drastically different from the regular fluorescence spectrum. Specifically, evcitatian profiles of bsg vibrations, which are important in vibrouic couplings, are analyzed.
