Chemical bonding in transition metal carbonyl clusters: complementary analysis of theoretical and experimental electron densities.

P Macchi, A Sironi - Coordination chemistry reviews, 2003 - Elsevier
In the last few years, the quantum theory of atoms in molecules has become the paradigm
for interpreting theoretical and experimental electron density distributions. Within this …

On the full topology of the Laplacian of the electron density

PLA Popelier - Coordination Chemistry Reviews, 2000 - Elsevier
In this work we briefly review the use of the function L (r), which is defined as minus the
Laplacian of the electron density,∇ 2ρ, in the context of the theory of 'atoms in molecules' …

[图书][B] Atoms in molecules

PLA Popelier, FM Aicken, SE O'Brien - 2000 - researchgate.net
1.1 What Is AIM?±The theory of``Atoms in Molecules''(AIM) is an interpretative theory which
aims to recover chemical insight from modern highresolution electron densities. 1 These …

Characterization of a dihydrogen bond on the basis of the electron density

PLA Popelier - The Journal of Physical Chemistry A, 1998 - ACS Publications
A new type of hydrogen bond, called a dihydrogen bond, has recently been introduced. In
this bond a hydrogen is donated to another (hydridic) hydrogen. We apply a set of criteria …

The electron pair

RFW Bader, S Johnson, TH Tang… - The Journal of Physical …, 1996 - ACS Publications
Eighty years have elapsed since Lewis introduced the concept of an electron pair into
chemistry where it has continued to play a dominant rôle to this day. The pairing of electrons …

MORPHY, a program for an automated “atoms in molecules” analysis

PLA Popelier - Computer Physics Communications, 1996 - Elsevier
The operating manual for a structured FORTAN 77 program called MORPHY is presented.
This code performs an automated topological analysis of a molecular electron density and …

Searching for saddle points of potential energy surfaces by following a reduced gradient

W Quapp, M Hirsch, O Imig… - Journal of computational …, 1998 - Wiley Online Library
The old coordinate driving procedure to find transition structures in chemical systems is
revisited. The well‐known gradient criterion,∇ E (x)= 0, which defines the stationary points …

Quantum molecular similarity. 1. BCP space

PLA Popelier - The Journal of Physical Chemistry A, 1999 - ACS Publications
We propose a new similarity measure operating in an abstract space spanned by properties
evaluated at bond critical points defined by the theory of Atoms in Molecules. Consequently …

Evaluation of net atomic charges and atomic and molecular electrostatic moments through topological analysis of the experimental charge density

A Volkov, C Gatti, Y Abramov… - … Section A: Foundations of …, 2000 - journals.iucr.org
The atoms in molecules (AIM) theory may be used to derive atomic charges, atomic volumes
and molecular dipole moments from the charge density. The theory is applied to theoretical …

Characterization of an agostic bond on the basis of the electron density

PLA Popelier, G Logothetis - Journal of organometallic chemistry, 1998 - Elsevier
Several conformations of CH3TiCl2+, C2H5TiCl2+ and C3H7TiCl2+ were selected for a
case study on agostic bonds. Ab initio wavefunctions have been generated at Hartree–Fock …
