Franck-Condon factors and r-centroids for certain band systems of astrophysical molecules SrF and ScF

Abstract

The Franck-Condon factors and r-centroids, which are very closely related to vibrational transition probabilities, have been evaluated by the more reliable numerical integration procedure for the bands of B2∑+ − X2∑+, F2∑+ − X2∑+ systems of SrF and C1∑+ − X1∑+, G1Π − X1∑+ systems of ScF molecules of astrophysical interest, using a suitable potential.
