Franck-Condon analysis of the photoelectron spectra of S2O−: Including Duschinsky effects

Franck-Condon analysis and spectral simulations were carried out on the first photoelectron band of S2O−. The accurate equilibrium geometric parameters, r(ss) = 0.1996 ± 0.0005 nm and r(so) = 0.1514 ± 0.0005 nm, of the X˜2A″ state of S2O−, are deduced by employing an iterative Franck-Condon analysis procedure in the spectral simulation.
