Abstract

Rotationally resolved dispersed fluorescene spectra from the 6¹ level of benzene have been used to probe intramolecular vibrational energy redistribution in the ground electronic state. The level 1₂ (E_vib=1986 cm^-1) and 1₃ (E_vib=2979 cm^-1) are observed to be each coupled to a single close-lying level. We propose that the pertubing levels are 5₂ in the case of 1₂ and 5₂1₁ in the case of 1₃. The coupling constant k₁₁₅₅ has been determined to be 1.4 cm^-1.
