High resolution continuum resonance Raman spectra of isotopically pure 79Br35Cl were recorded with excitation by several argon ion laser lines from the visiblr to the UV region. With excitation in the UV region spectra also of higher overtones could be observed. The complex rovibrational structures are explained in terms of Q branches, unresolved S bands and S band heads, unresolved Q branches and corresponding hot band transitions. The experimentally observed spectra were simulated using both the conventional and time-dependent quantum theory. The simulations of the observed spectra together with results from depolarization ratio measurements allowed us to discuss the excited state potential functions involved in this type of resonance Raman scattering. The high sensitivity of resonance Raman band shapes to changes in the position of excited potential curves gives the possibility of determining the potential functions of the excited states 1Π1 and 3Π0+. The spectral features of the fundamental Raman band could be explained assuming nonresonant Raman scattering resulting from adjacent highly lying states.©Anita Publications. All rights reserved.
