Electron transfer — (ET) is the process by which an electron moves from one atom or molecule to another atom or molecule. ET is a mechanistic description of the thermodynamic concept of redox, wherein the oxidation states of both reaction partners change. Numerous… … Wikipedia
Inner sphere electron transfer — Inner sphere or bonded electron transfer[1] proceeds via a covalent linkage between the two redox partners, the oxidant and the reductant. In Inner Sphere (IS) electron transfer (ET), a ligand bridges the two metal redox centers during the… … Wikipedia
Proton-coupled electron transfer — (PCET) is a reaction mechanism that is thought to be common in redox reactions. It involves the concerted transfer of an electron and proton to or from a substrate.[1][2] In PCET, the proton and the electron (i) start from different orbitals and… … Wikipedia
Outer sphere electron transfer — Outer sphere refers to an electron transfer (ET) event that occurs between chemical species that remain separate intact before, during, and after the ET event.[1] In contrast, for inner sphere electron transfer the participating redox sites… … Wikipedia
Proton coupled electron transfer — (PCET) is an electrochemical reaction mechanism in which an electron and proton is simultaneously moved in a concerted mechanism. [Huynh, M. H.; Meyer, T. Chem. Rev. 2007, 107 , 5004 5064.] Mechanism Proton coupled electron transfer (PCET) is… … Wikipedia
Proton transfer reaction - mass spectrometry — (PTR MS) is a very sensitive technique for online monitoring of volatile organic compounds (VOCs) in ambient air developed by scientists at the Institut für Ionenphysik at the Leopold Franzens University in Innsbruck, Austria [A. Hansel, A.… … Wikipedia
Negative electron-transfer dissociation — (NETD) is an ion/ion reaction in which an electron from an anionic specie is transferred to cationic reagent.[1] Following this transfer event, the electron deficient anion undergoes internal rearrangement and fragments. NETD is the ion/ion… … Wikipedia
Electron transport chain — The electron transport chain in the mitochondrion is the site of oxidative phosphorylation in eukaryotes. The NADH and succinate generated in the citric acid cycle are oxidized, providing energy to power ATP synthase … Wikipedia
reaction centre — The site in the chloroplast that receives the energy trapped by chlorophyll and accessory pigments, and initiates the electron transfer process … Dictionary of molecular biology
oxidation–reduction reaction — ▪ chemical reaction Introduction also called redox reaction any chemical reaction in which the oxidation number of a participating chemical species changes. The term covers a large and diverse body of processes. Many oxidation– reduction… … Universalium
