In the case of NH3, coupling occurs mainly through the HOMO 3a1-levels (N lone pair), whereas with H2O the main contribution arises from 蟽-bond formation of the second highest occupied orbital (3a1 O2pz). Results on the bond energies, electron populations and orbital energies are in ...
The EED concept was used to study the quality of wavefunction tails; the basis-set dependence of ab initio MO for NH3 was studied from EED. The EED for the nonbonding orbital (3a1) increases dramatically with the size of basis sets, whereas that for the bonding orbital (1e) shows ...
