Intensity distribution in the bands of theD 1Π →X 1Σ+ system of SnO

Investigation of A−X Band System of Astrophysically Significant Molecule BS

“…1 Accurate values of FCFs and r-centroids are essential to arrive at the variation of electronic transition moment, band strength and vibrational temperature of the source. 2,3 The researchers pay attention to the theoretical work on the diatomic molecule BS for many years. Recently, the potential energy of the electronic states X, C and G of BS radical were calculated by the Davidson-modified high resolution internal-contraction multiple-reference configuration interaction method.…”

Franck-Condon factors and r-centroids for certain band systems of SiD, SiF and SiN molecules of astrophysical interest

“…The Franck-Condon (FC) factors and r-centroids are important for determining the variation of electronic transition moment with internuclear separation (Rajamanickam 1985;Rajamanickam et al 1993).…”
