Some useful data for the astrophysical molecules AlS and BS
چکیده انگلیسی
The vibronic (vibration-electronic) transition probability parameters such as Franck-Condon (FC) factors and r-centroids of diatomic molecular species could be useful in the identification of molecular lines and in the estimation of relative abundance of the species in astrophysical sources. In this study, they have been evaluated for the electronic transitions A2Σ+→X2Σ+ and A′2Σ+→X2Σ+ of AlS and C2Πr→X2Σ+, E2Σ+→X2Σ+ and B2Σ+→A2Πi of BS molecules, by a numerical integration procedure using a suitable potential. The physical and astrophysical significances of our evaluated FC factors and r-centroids have also been discussed, which would be helpful in the prediction of the presence of AlS and BS molecules in umbral sunspots and other celestial bodies.
