Due to the use of a deformation step instead of a localization step, the influence of the environment on each separate molecule can be studied in detail. The generated orbital set for the whole molecular system is strictly equivalent to a set of canonical orbitals and is a subsequent energy decomposition of intermolecular interactions into electrostatic, exchange repulsion, and orbital interaction, well beyond dimer systems. Beyond this, the correspondence of the individual orbitals to the initial monomer .

ABSTRACT: We present a modified definition of the Electron Pair Localization Function (EPLF), initially defined within the framework of quantum Monte Carlo approaches [Scemama, A.; Caffarel, M.; Chaquin,J. Chem. Phys. 2004, 121, 1725] to be used in Density Functional Theories (DFT) and ab initio wave-function-based methods. This modified version of the EPLF—while keeping the same physical and chemical contents—is built to be analytically computable with standard wave functions or Kohn-Sham representations. It .

1. Introduction The bonding in many molecular systems is not fully explained by considering a single Lewis structure. As a classical example we can mention the conjugated hydrocarbons for which a straightforward application of the valence concepts led Huggins to propose chimerical structures [1]. Within the standard quantum chemical approaches such systems are understood either as the superposition of resonant valence-bond structure [2] or in terms of occupied molecular orbital delocalized over the whole .

1. Introduction The two-particle electron–electron interaction, 1rri j , with its singularity for ri j 0, is the main source of the complexity of molecular wavefunctions c : long configuration-interaction ŽCI. expansions in terms of extended one-particle basis sets are necessary to properly describe the correlation cusp of c at ri j 0 w1x. One possibility to overcome this difficulty is the explicit introduction of the inter-electronic coordinates ri j into c ; while being computationally demanding, this .
