Computing Exchange Coupling constants in Transition metal complexes with Tensor Product Selected Configuration Interaction
Arnab Bachhar, Nicholas J. Mayhall
Transition metal complexes present significant challenges for electronic structure theory due to strong electron correlation arising from partially filled -orbitals. We compare…
