We begin by discussing the interaction induced dipole moment of the He•••H 2 system. Following the approach of Heijmen et al., we examined the same geometries: the angular dependence of the interaction-induced dipole moment for the angle between the molecular axis and the line connecting the centers of masses ranging from 0 • to 90 • , and its two components: perpendicular and parallel to the intermolecular axis, at distances of 5a 0 (which corresponds to the van der Waals minimum region) and 7a 0 , respectively. Figures and present the angular dependence of the induced dipole compared with the finite-field (FF) methods and its decomposition into the polarization and exchange parts. Interestingly, the induced dipole moment is relatively insensitive to electronic correlation effects. Even the HF description alone provides a reasonably good approximation, overestimating the CCSD(T) results by 23% at 7a 0 and 13% at 5a 0 for the linear geometry presented in Table . The supermolecular DFT calculations agree with CCSD(T) quite well for 5a 0 , but as the atom•••molecule separation Table : Values of the interaction induced dipole moment component along the intermolecular axis specified by the vector ⃗ R (pointing from the center of mass of monomer A to the center of mass of monomer B for a system denoted as A Table : Decomposition of the first-order interaction-induced dipole moment components along the intermolecular axis into polarization (∆µ pol,r ) and exchange parts (∆µ exch,r ). All values of dipole moment are given in 10 -3 ea 0 . Note that the propSAPT and FF-SAPT columns should match exactly. propSAPT and FF-SAPT(DFT) values are, to some extent, expected to differ due to the ALDA kernel approximation. increases, supermolecular DFT starts to deviate from CCSD(T) quite significantly.
