electrostatic bond
41Electronic effect — An electronic effect influences the structure, reactivity, or properties of molecule but is neither a traditional bond nor a steric effect. [G. L. Miessler and D. A. Tarr “Inorganic Chemistry” 3rd Ed, Pearson/Prentice Hall publisher, ISBN 0 13… …
42Enzyme catalysis — is the catalysis of chemical reactions by specialized proteins known as enzymes. Catalysis of biochemical reactions in the cell is vital due to the very low reaction rates of the uncatalysed reactions. The mechanism of enzyme catalysis is similar …
43Hyperconjugation — In organic chemistry, hyperconjugation is the interaction of the electrons in a sigma bond (usually C–H or C–C) with an adjacent empty (or partially filled) non bonding p orbital or antibonding π orbital or filled π orbital, to give an extended… …
44Molecular dynamics — (MD) is a computer simulation of physical movements of atoms and molecules. The atoms and molecules are allowed to interact for a period of time, giving a view of the motion of the atoms. In the most common version, the trajectories of molecules… …
45VSEPR theory — Valence shell electron pair repulsion (VSEPR) theory is a model in chemistry used to predict the shape of individual molecules based upon the extent of electron pair electrostatic repulsion.[1] It is also named Gillespie–Nyholm theory after its… …
46Molecular graphics — (MG) is the discipline and philosophy of studying molecules and their properties through graphical representation.[1] IUPAC limits the definition to representations on a graphical display device .[2] Ever since Dalton s atoms and Kekulé s benzene …
47chemistry — /kem euh stree/, n., pl. chemistries. 1. the science that deals with the composition and properties of substances and various elementary forms of matter. Cf. element (def. 2). 2. chemical properties, reactions, phenomena, etc.: the chemistry of… …
48protein — proteinaceous /proh tee nay sheuhs, tee i nay /, proteinic, proteinous, adj. /proh teen, tee in/, n. 1. Biochem. any of numerous, highly varied organic molecules constituting a large portion of the mass of every life form and necessary in the… …
49Molecular mechanics — A force field is used to minimize the bond stretching energy of this ethane molecule. Molecular mechanics uses Newtonian mechanics to model molecular systems. The potential energy of all systems in molecular mechanics is calculated using force… …
50Champ de force (chimie) — Pour les articles homonymes, voir champ de force. Un champ de force peut par exemple être utilisé afin de minimiser l énergie d étirement de cette molécule d éthane. Dans le cadre de la m …
