Molecular electrostatic potentials of divalent carbon(0) compounds

Physical Chemistry Chemical Physics, 2008
The molecular electrostatic potentials of divalent carbon(0) and divalent carbon(ii) compounds are calculated and the results are compared with theoretically predicted proton affinities and complexation energies with BH(3).

Hydrogen Bonding, Electrostatic Potential, and Molecular Design

Journal of Chemical Information and Modeling, 2009
The V(alpha)(r) descriptor was introduced and shown to be an effective and useful predictor of hydrogen bond acidity. V(alpha)(r) is defined as the electrostatic potential at a distance, r, from the donor hydrogen on an axis defined by the nuclei of the hydrogen atom and the atom to which it is bonded.

Molecular electrostatic potentials and electron densities in nitroazacubanes

The Journal of Chemical Physics, 2004
Successive introduction of nitrogen atoms in the cubyl corners instead of C–NO2 groups of octanitrocubane (CNO2)8, the most powerful explosives known to date, leads to a class of energy-rich compounds known as nitroazacubanes. In present work the ab initio Hartree–Fock and hybrid density functional calculations have been carried out on the possible ...

Electrostatic molecular potentials in hydrogen-bonded systems

Theoretica chimica acta, 1978
A study is made of the modifications of the electrostatic molecular potential brought about by hydrogen bonding both in the hydrogen-bond region itself and in the external regions of the proton-acceptor and proton-donor molecules. Systems up to four successive units in a chain of donor-acceptors are considered.

Molecular Recognition via Electrostatic Potential Topography

1996
The chapter focuses on molecular recognition via electrostatic potential. A sound knowledge of structure-and energy-related information is available from the experimental and computational studies mentioned in the chapter. A variety of theoretical models have been developed forunderstanding the weak intermolecular interactions.

Molecular wire conductance: Electrostatic potential spatial profile

The Journal of Chemical Physics, 2000
We have studied the effect of the electrostatic potential on the current across a one-dimensional tight-binding molecular wire by solving self-consistently the Poisson and Schrödinger equations. The results indicate that electrostatic effects on the current are very important in the nonlinear regime.

Molecular electrostatic potentials for large systems

1996
This chapter discusses several techniques used to investigate the reactivity of cluster surfaces and solid surfaces. The first approach used was the atomic net charges generated with different population analyses to find the reactive sites. This turned out to be insufficient.

Topological analysis of the molecular electrostatic potential

The Journal of Chemical Physics, 1999
The topology of the molecular electrostatic potential of 18 molecules, calculated in the framework of Kohn–Sham density functional theory, is studied. For the location of the different kinds of critical points a newly developed search algorithm is applied. A chemical interpretation of the critical points in terms of lone pairs, π bonds, hybrid orbitals

Molecular surface electrostatic potentials of anticonvulsant drugs

International Journal of Quantum Chemistry, 1998
The computed molecular surface electrostatic potentials of a group of anticonvulsants of various chemical types were investigated with the objective of identifying common features that may be related to their activities. The calculations were carried out with the density functional B3P86/6-31G* procedure, using HF/STO-3G*-optimized geometries. Analysis
