Excitation and fluorescence spectra of benzonitrile-benzene and toluene complexes seeded in helium andexpanded in a supersonic free jet reveals two types of transition attributed to the coexistence of twoisomeric forms. One consists of narrow bands in both excitation and emission and is characteristic ofwealdy perturbed van tier Waals complexes. The other involves broadened absorption and gives rise to anexciplex type emission.
