The Electron Correlation Problem

Opacity

“…Hehre (1986) discussed computational methods, selection of models, and performance of models for calculation of equilibrium geometries, vibrational frequencies, thermochemical stabilities, electric dipole moments, and charge distributions. The electron correlation problem was the subject of reviews by McWeeny (1992), Paldus (1992a) (unitary group approach), Karwowski (1992) (configuration interaction approach), Paldus (1992b), Bartlett and Musial (2007) (coupled cluster theory), and Wilson (1992a,b,c,d) (perturbation theory). The diagrammatic representation of many-body perturbation theory as applied to atomic structure was the subject of Lindgren (1998), who also described the coupled-cluster approach.…”
