Abstract:

The Franck-Condon factors and r-centroids, which are very closely related to relative vibrational transition probabilities, have been computed by the more reliable numerical integration procedure for the bands of system of SiD, of SiF and system of SiN molecules of astrophysical interest, using a suitable potential.
