The first observation of a vibrationally (and rotationally) resolved resonance hyper-Raman spectrum is reported. Inelastic scattering spectra in the UV are observed when blue radiation ( a 4 16 nm) is focused in ammonia (1-8 atm). Twice the corresponding incident frequency is resonant with the secon

โฆ Synopsis
The first Raman and hyper-Raman spectra of chloro-and iodobenzene for excitation resonant with the L, electronic state are reported. Both the weakly perturbing chlorine and strongly perturbing iodine substituents induce the same type of Raman activity. The spectra are dominated by the yg, fundamental and other totally symmetric vibrational modes ( Franck-Condon activity) and show little evidence of significant vibronic behavior.
