Atomic partial charges cannot be physically measured but they play a significant role in many chemical theories and theoretical models. Therefore, they are, evaluated from experimentally acquired properties or calculated by quantum chemistry computational methods. This study is focused on determining ...

There’s a hidden layer of detail beneath chemical structures that students new to organic chemistry often miss. I’m talking about partial charges. Although each of these bonds appears to be covalent, the electronegativity of each atom determines how “greedy” it is for electrons – and this...
It is shown that the use of atomic partial charges in the analysis of the nature of the interatomic interactions may be misleading because they do not... A Kovács,C Esterhuysen,G Frenking - 《Chemistry》 被引量: 302发表: 2005年 Coulombic interactions between partially charged main-chain at...

In general chemistry, what do weak acids do? a. accept a proton b. donate a proton Adding multiple phosphate groups to molecules A) increases charge repulsion. B) decreases the stability of a molecule. C) weakens the bonds between other atoms. D...

However, if the applications which take its place are to be satisfied by a lead–acid product (probably VRLA), rather than by a battery of a different chemistry, a program of development as successful as that mounted for deep cycle duty will be required. The present phase of the Advanced ...
The electrostatic potential of a molecule originates from the atomic partial charges. While the electrostatic reaches into the long range, the partial charges also contribute to the molecular recognition in the short range where they are the driving forces of polar interactions (hydrogen bonding and...
