Title: Perspective: Multireference coupled cluster theories of dynamical electron correlation

Abstract

Predicting the electronic structure and properties of molecular systems that display strong electron correlation effects continues to remain a fundamental theoretical challenge. This perspective investigates the recent progress and current challenges in multireference wave function methods for dynamical electron correlation, honing in on systematically improvable methods that go beyond the limitations of configuration interaction and perturbation theory
