Laser-induced fluorescence and resonance Raman spectra of interhalogen diatomics isolated in inert matrices at 12 K

Abstract

Laser-induced fluorescence and resonance Raman spectra were obtained from iodine monochloride and bromine chloride isolated in argon matrices and from BrCl in a krypton matrix, leading to values of ω e , ω e x e , and T 0 for these matrix isolated species. A strong resonance Raman progression from iodine monobromide isolated in an argon matrix led to values of ω e and ω e x e for that molecule. Isotopic splitting was resolved in fluorescence spectra of BrCl and ICl and in the resonance Raman series from isolated IBr. Spectroscopic constants obtained for these molecules were compared to the reported gas phase values, and conclusions were drawn concerning fluorecence and Raman effects for homonuclear and heteronuclear halogen diatomics in the gas phase and isolated in inert gas matrices.
