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

Multireference coupled cluster study of the oxyallyl diradical
Adiabatic singlet-triplet gap of the oxyallyl diradical has been studied by multireference Brillouin-Wigner and Mukherjee's coupled cluster methods (BWCC and MkCC). The results demonstrate the necessity to include connected...
