Abstract

High-resolution polarized and depolarized continuum resonance Raman spectra of isotopically pure 127 I 35 Cl for fundamental and overtone transitions Δ&ngr; = 1-4 with excitation from the green to the blue spectral region have been used to determine the repulsive part of the potential function 3 &Pgr; 0+ as well as the pure repulsive potential function 1 &Pgr; 1 . The latter is responsible for the predissociation of the 3 &Pgr; 0+ state. The continuum resonance Raman spectra are highly sensitive to the position and shape of the excited state potential functions and hence allow an accurate determination of these functions. The experimental spectra were simulated applying time dependent as well as time independent second-order perturbation theory.
