PY - 2016/03/30 Y2 - 2024/03/29 TI - Reaction Rate Maxima at Large Distances between Reactants JF - CHIMIA JA - Chimia VL - 70 IS - 3 SE - Scientific Articles DO - 10.2533/chimia.2016.177 UR - https://www.chimia.ch/chimia/article/view/2016_177 SP - 177 AB - One commonly thinks that two reactants need to come very close to one another in order for a chemical reaction to occur. This is true for most reaction types, but electron transfer is an exception in this regard. It is a well-documented fact that electron transfers can occur over long distances (?15 Å), but it is much less well-known that theory predicts a regime in which electron transfer rates in crease with increasing distance between reactants. This contribution explains the physical origin of this counter-intuitive behavior, and it identifies a set of conditions that might facilitate its experimental observation. ER -
