✦ Synopsis
Second-order Moller-Plesset calculations employing large basis sets which include bond functions are presented for (NH,)2. The H-bonded structure is found to be more stable than a cyclic configuration. The nuclear quadrupole wupling constants for the r4N nuclei are shown to be sensitive to rotational motions of the monomers.

General guidelines for development of small but efficient basis sets for intermolecular interaction calculations have been proposed and tested for simple model systems. It has been demonstrated that the use of overlap matched atomic orbitals (OMAO) leads to significant improvement in the first-order
The supermolecule interaction energies at the self-consistent field and the second-order Moller-Plesset perturbation theory levels are analyzed using the polarization approximation perturbation theory of intermolecular interactions. The results for the He-H+ complex show that the perturbation expans
