Abstract: 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 C2Σg+←B2Σu+ transitions of CS2+ 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 C2Σg+←B2Σu+ transition, and to estimate the validity of the rotation constants and the bond length of C2Σg+ state given in the previous studies. The photodissociation mechanism via the C2Σg+←B2Σu+transitions of CS2+ ions has also been discussed.

Key words: CS2+ ions, Franck-Condon factors, Photodissociation spectra
