摘要：

Laser-induced fluorescence spectra of jet-cooled chlorotoluene molecules are reported for the S1 state. The fluorescence excitation spectrum of m-chlorotoluene shows some low-frequency bands up to 200 cm-1 above the S1 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 C-Cl stretching modes for the o-, m- and p-chlorotoluene molecules are 341, 378 and 360 cm-1 respectively in the S1 state.
