Abstract:
The Franck-Condon (FC) factors (transition probabilities) and r-centroids have been evaluated by the reliable numerical integration procedure for the bands of the A^3 φ_4 --> X^3 φ_4 system of astrophysical molecule CoH, using a suitable potential. The dissociation energy D^0_0 = 2.5 +/- 0.05 eV for the electronic ground state of CoH has been estimated by fitting Hulburt-Hirschfelder function to the experimental potential energy curve, using the correlation coefficient.
