Abstract:
In view of the renewed interest in the electronic spectra of the AlO molecule, which is of both astrophysical and aeronomical interest, a systematic analysis of the available spectral data is carried out. A valid and consistent set of vibrational constants are derived for the A and D states of the molecule. Potential curves (Morse and RKRV) are obtained for the X, A, C and D states. Franck-Condon (FC) intensity factors and r-centroids are reported for the C---X, D---X and D---A transitions. The calculated FC-factors are used to explain the intensity distribution of the bands in the various systems
