Laser-induced fluorescence spectra of the non symmetrical isotopomers of CuCl2

Investigations of the ground state of CuCl2 have been pursued recording laser induced fluorescence spectra on a BOMEM DA3 Fourier transform spectrometer in the range 10000-16500 cm-1. In this work, we specially extend the study to the non symmetrical isotopomers 35Cl63Cu37Cl and 35Cl65Cu37Cl. Band-by-band and polynomial fits allowed us to determine rotational and vibrational constants in the range v''1=0-9. v''=0-6 that will be compared to the constants of the main symmetrical isotopomers 63Cu35Cl2. An approximate Valence Force Field model is tested and discussed
