Single-root multireference Brillouin-Wigner coupled-cluster theory. Rotational barrier of the ethylene molecule

Recently developed single-root multireference Brillouin-Wigner coupled cluster (MR BWCC) theory is applied to study the rotational barrier of the ethylene molecule. The method belongs to a broad family of state-selective coupled...

State-Specific Brillouin-Wigner Multireference Coupled Cluster Study of the Singlet-Triplet Separation in the Tetramethyleneethane Diradical.

The potential energy curves for the twisting of tetramethyleneethane in its lowest singlet and triplet states were calculated by the state-specific two-reference Brillouin-Wigner coupled-cluster method with single and double excitat...

Gas-phase study of the C-C coupling of naphthol catalyzed by CuII-TMEDA

The gas-phase study of the title reaction shows that the coupling proceeds on binuclear clusters of copper. Stabilities of the clusters are enhanced by nitrogen ligands and depend on the counterion....

Communication: Application of state-specific multireference coupled cluster methods to core-level excitations

The concept of the model space underlying multireference coupled-cluster (MRCC) formulations is a powerful tool to deal with complex correlation effects for various electronic states. Here, we demonstrate that iterative state-specif...
