WebOpen-shell singlet Since the singly excited determinants effectively relax the orbitals in a CCSD calculation, non-canonical HF orbitals can also be used in coupled cluster methods.This allows for example the use of open-shell singlet states (which require two Slater determinants) as reference for a coupled cluster calculation.

WebSuch change can be explained by a subtle balance between two types of antiferromagnetic spin–spin coupling along the π-conjugated macrocycles. The dications of DTI-MC3 and DTI-MC4 turned out to be open-shell singlet diradical dications, with a singlet–triplet energy gap of −2.90 and −2.60 kcal mol −1, respectively.
