Abstract
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.
