Using energy decomposition analysis from correlated wavefunction theory to characterize a range of hydrogen, halogen, and tetrel bonds: the relative importance of electrostatics, charge-transfer and polarization.
Second-order Møller-Plesset theory (MP2) is the simplest wavefunction-based treatment of electron correlation and is a good compromise between accuracy and efficiency for evaluating the strength of many non-covalent intermolecular interactions. It has also been improved in accuracy and robustness by regularized methods...
