Ab initio study and spectral simulation of the X̃1A1←X̃2B1 photodetachment processe of dichlorocarbene anion

- We present an analytical expression to calculate the two-dimensional Franck-Condon integrals.
- The photoelectron spectrum is simulated and the role of Duschinsky effects is considered.
- The electron affinities of dichlorocabene are calculated.
