説明
Abstract Laser-induced fluorescence spectra of jet-cooled chlorotoluene molecules are reported for the S 1 state. The fluorescence excitation spectrum of m -chlorotoluene shows some low-frequency bands up to 200 cm −1 above the S 1 origin, which are assigned to internal rotational modes of the methyl group. Beyond 300 cm −1 and up to approximately 1500 cm −1 sharp vibrational bands are observed, which are assigned by measurement of the dispersed fluorescence spectrum on excitation of each vibrational band. The vibrational energies of the CCl stretching modes for the o- , m - and p -chlorotoluene molecules are 341, 378 and 360 cm −1 respectively in the S 1 state.
