where X denotes a given property that is measured (calculated) at the given geometry for the dimer complex and separate monomers. Interaction-induced properties (from now on, we will use the abbreviation IIP) have been studied for quite a long time, notably starting with Richard Feynman and Hans Hellmann independently in the late 1930s. Much later, Hirschfelder and Eliason 45 performed a detailed analysis of the second-order corrections in the V operator for two hydrogen atoms. Buckingham studied polarizability and hyperpolarizability of a pair of atoms and used double perturbation theory for the leading asymptotic terms. In 1990, Hunt 47 rigorously proved Feynman's hypothesis on the behavior of dipole moments and derived closed formulas for the effects of polarization on molecular properties in terms of response functions in the asymptotic region. As we briefly stated before, one of the primary reasons for studying dipole moment surfaces is collision-induced absorption. In this paper, we consider only the first-order properties (i.e., linear with respect to the external field strength associated with X), which can be described by the Hellmann-Feynman theorem. To this end, we start with the approach introduced by the group of Jeziorski in which the IIP are computed directly, without the necessity of computing the dimer property, and adopt it to the SAPT formalism, as a series of perturbations in X.
