Calculation of the franck-condon factors for the transitions of CS+2 ions and comparison with related photodissociation spectra

On the basis of the approximation of harmonic oscillation between SC and S for the symmetric stretching vibration of the CS2+ ions, the Franck-Condon factors for the C˜2Σg+←B˜2Σu+ transitions of CS+2 ions have been calculated using the potential curves and wavefunctions of the harmonic oscillator. The calculation results have been used for comparison with the photodissociation spectra via the C˜2Σg+←B˜2Σu+ transition, and for estimating the validity of the rotation constants and the bond length of C˜2Σg+ state given in the previous studies. The photodissociation mechanism via the C˜2Σg+←B˜2Σu+ transitions of CS+2 ions has also been discussed.
