A Study of Perturbations of the A1Σu + State of Na2

High resolution Fourier spectrometry techniques have been used to study the A1Σ+u state, which is perturbed by the b3Πu state of the Na2 molecule. This study was achieved by means of exciting the B1Πu state from the X1Σ+g ground state by 4880 Å and 4965 Å lines of an Ar+ laser. The excitation is followed by collisional transfer energy produced between B1Πu and (2)1Σ+g states ν, which led to the population of the vibrational levels of the (2)1Σ+g state v. The analysis of the collision-induced system (2)1Σ+g −A1Σ+g enabled us to study, in detail, the perturbations of 11 vibrational levels from v = 0 to v = 10 of the A1Σ+u state.
