Bond Paths Are Not Chemical Bonds

The Journal of Physical Chemistry A, 2009
This account takes to task papers that criticize the definition of a bond path as a criterion for the bonding between the atoms it links by mistakenly identifying it with a chemical bond. It is argued that the notion of a chemical bond is too restrictive to account for the physics underlying the broad spectrum of interactions between atoms and ...

ChemInform Abstract: Bond Paths and Bond Properties of Carbon‐Lithium Bonds.

ChemInform, 1987
Twenty-three organolithium compounds were analyzed by using the topological theory of molecular structure. The geometry of each compound was first optimized, making use of the 3-21G basis set. Then integrated lithium charges and quantities characterizing the carbon-lithium bond critical point, such as rho/sub c/ (C-Li), del/sup 2/rho/sub c/(C-Li), and ...

Lithium Bond Chemistry in Lithium-Sulfur Batteries.

Angewandte Chemie, 2017
The lithium-sulfur (Li-S) battery is a promising high-energy-density storage system. The strong anchoring of intermediates is widely accepted to retard the shuttle of polysulfides in a working battery.

Multicenter bonds, bond valence and bond charge apportionment

Journal of Molecular Structure: THEOCHEM, 1997
Abstract In the same way that the valence of an atom issues from the definition of bond index, we show here that the three-center bond index lends itself to the definition of a bond valence. Within the charge of a bond, we show that its self-charge (i.e., the amount of electrons kept by the atoms involved in the bond) is split in such a way that the ...

Organocatalysis in Inert C-H Bond Functionalization.

Chemical Reviews, 2017
As two coexisting and fast-growing research fields in modern synthetic chemistry, the merging of organocatalysis and C-H bond functionalization is well foreseeable, and the joint force along this line has been demonstrated to be a powerful approach in ...

Understanding organofluorine chemistry. An introduction to the C-F bond.

Chemical Society Reviews, 2008
Fluorine is the most electronegative element in the periodic table. When bound to carbon it forms the strongest bonds in organic chemistry and this makes fluorine substitution attractive for the development of pharmaceuticals and a wide range of ...

Hydrogen bonds, improper hydrogen bonds and dihydrogen bonds

Journal of Molecular Structure: THEOCHEM, 2003
Abstract The structures, interaction energies and vibrational spectra of a large number of molecular complexes, formed by binary combination of the covalent hydrides of some of the elements of the first two rows of the periodic table, have been determined by means of ab initio molecular orbital theory at the MP2 level, using the 6-311++G(d,p) basis ...

Bond-orientational order in liquids and glasses

, 1983
Bond-orientational order in molecular-dynamics simulations of supercooled liquids and in models of metallic glasses is studied. Quadratic and third-order invariants formed from bond spherical harmonics allow quantitative measures of cluster symmetries in
