- Abstract
Astrophysical applications are broadened by the emerging consensus on the vibration-electronic (vibronic) transition probability parameters such as Franck - Condon (FC) factors & r - centroids of some molecular species like CN, which could be useful in the identification of molecular lines and in the estimation of relative abundance of the species in various celestial bodies especially in the interstellar medium. Such important parameters, that is FC factors and r - centroids, have been computed by a reliable numerical integration procedure for the bands of E ² ∑+ - X ²∑+, D ²Πi - A ²Πi, E ²∑+ A ²Πi, F ²Δr - A ²Πi and J ²Δi - A ²πi systems of astrophysical molecule CN, using a suitable potential. For E - X system, the improved values of FC factors from the revised molecular constants are given along with the already reported values.
