Abstract
Abstract
The vertical and adiabatic electronic spectra of dithiosuccinimide have been investigated by means of multi-reference Møller–Plesset perturbation theory and combined densitiy functional/multi-reference configuration interaction methods. Geometries of the electronic ground state and several low-lying excited states have been optimised at the level of time-dependent density functional theory. We have determined spin-orbit coupling for correlated wavefunctions utilising a non-empirical spin-orbit mean-field approach. Because of the two thiocarbonyl groups present in the molecule, dithiosuccinimide exhibits a dense spectrum of low-lying valence states. The first two excited singlet states (S
1 and S
2) originate from n → π* excitations. Nearby, three triplet states are located, two n → π* states (T
1 and T
2), and a π → π* triplet excitation (T
3). The experimentally observed strong absorption band with maximum at 3.96 eV arises from the π → π* excited 1
B
2 (S
3) state. Computed radiative lifetimes are presented for the experimentally known phosphorescence from the n → π* excited T
1 state. Further, we find nearly equal probabilities for the spin-forbidden S
0 → T
2 and the spin-allowed S
0 → S
1 transitions in absorption. On these grounds, we assign band number 3 in the spectra measured by Meskers et al. [J. Phys. Chem.
99 (1995) 1134] to this spin-forbidden transition.
