Some vibrational bands of B-X system of AlO molecule in the sunspot spectra

Abstract

Vibrational transition probabilities, namely Franck-Condon factors and average r centroids, have been evaluated using an approximate analytical method for the B-X system of the AIO molecule. RKRV potential energy curves for X2Sigma(+) and B2Sigma(+) states of AlO have been constructed using the latest spectroscopic data. The value of average r centroids for the band have been found to increase linearly with the corresponding wavelengths
