【Abstract】 On the basis of the approximation of harmonic oscillation between SC and S for the symmetric stretching vibration of the CS+2 ions,the Franck-Condon factors for the 2X+g 2X+u 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 2X+g 2X+u transition,and to estimate the validity of the rotation constants and the bond length of 2X+g state given in the previous studies.The photodissociation mechanism via the 2X+g 2X+u transitions of CS+2 ions has also been discussed.更多还原
