摘要: Abstract A comprehensive analysis of the influence Boys and Bernardi counterpoise correction on calculated incremental static electric properties (dipole moment, polarizability first-order hyperpolarizability) has been carried out for selected hydrogen-bonded complexes. The model dimeric systems consisting HF, H 3 N 2 CO molecules have chosen as a case study. Calculations components dipole using diffuse Dunning’s basis sets aug-cc-pVXZ (X = D, T, Q, 5) d-aug-cc-pVXZ Q) performed employing various ab initio methods: MP2, MP2-F12, CCSD, CCSD(T) CCSD(T)-F12.
