Domain-Based Local Pair Natural Orbital Second-Order Møller-Plesset Perturbation Theory, and the Development of its Analytical Gradient
(2020-08-18)
Dynamic electron correlation methods are known to have a computational cost that scales with a high power of the system size: for example, O(N5) for second-order Møller-Plesset perturbation theory (MP2), and ......
Efficient approximations for the ab initio calculation of nuclear magnetic resonance shielding tensors
(2022-02-02)
Nuclear magnetic resonance (NMR) spectroscopy is an essential analytic technique in chemical, pharmaceutical, and biomedical research and materials sciences. The information that NMR provides about the molecular structure ......
