Abstract:	Vibrational transition probabilities-namely, Franck-Condon factors and $\bar r$ -centroids-have been evaluated using an approximate analytical method for theD-X system of SiS. Morse potential energy curves forD ¹ andX ¹⁺ states of SiS have been constructed using the latest spectroscopic data. The value of $\bar r$ -centroids for the band have been found to decrease linearly with the corresponding wavelength.
