Second-order perturbation theory with a CASSCF reference function

TL;DR: In this article, the second-order perturbation theory based on a CASSCF reference state is derived and implemented, where the first-order wave function includes the full space of interacting states and the zeroth-order Hamiltonian reduces to the MOller-Plesset Hamiltonian for a closed shell reference state.

TL;DR: The NWChem computational chemistry suite is reviewed, including its history, design principles, parallel tools, current capabilities, outreach, and outlook.
Journal ArticleDOI

Self-consistent perturbation theory: Open-shell states in perturbation-dependent non-orthogonal basis sets This work was partly supported by the Institute of Low Temperatures and Structure Research of the Polish Academy of Sciences under contract No. MR-I.9.4.3/2.

TL;DR: In this paper, the perturbation equations of the self-consistent density matrix perturbations theory were derived for open-shell configurations in the restricted Hartree-Fock approximation.

NWChem: Past, Present, and Future

Edoardo Aprà, +113 more
TL;DR: The NWChem computational chemistry suite as discussed by the authors provides tools to support and guide experimental efforts and for the prediction of atomistic and electronic properties by using first-principledriven methodologies to model complex chemical and materials processes.
