Abstract

We show that to obtain accurate potential curves by perturbing geminal-type wave functions, it is insufficient to restrict the geminals to their singlet-coupled states. Including triplet excited geminals to form four-electron singlets via the Serber coupling is essential to describe processes involving the simultaneous dissociation of two non-isolated single bonds.
