Dynamic electron correlation methods are known to have a computational cost that scales with a high power of the system size: for example, <em>O</em>(<em>N</em><sup>5</sup>) for second-order Møller-Plesset perturbation ...
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 ...
