Extended Dynamically Weighted CASPT2: The Best of Two Worlds

[Image: see text] We introduce a new variant of the complete active space second-order perturbation theory (CASPT2) method that performs similarly to multistate CASPT2 (MS-CASPT2) in regions of the potential energy surface where the electronic states are energetically well separated and is akin to e...
