Abstract:
In molecular astrophysics, the Franck-Condon (FC) factors and r-centroids are essential for the interpretation of spectral intensities in terms of emitting astrophysical source conditions. They have been evaluated for the band systems a 3Πr - X 1Σ+, d3Δni - X 1Σ+- X 1Σ+, e 3Σ- - X 1Σ+, A' 1Σ+ - X 1Σ+ and d3Δni and - a 3Πr of astrophysical molecule CS. The physical and astrophysical significances of our evaluated FC factors and r-centroids are discussed. The FC factor values of a - X system have been compared with the values of FC factors reported by Reddy et al. (2003).
