Historique

Eyring et Polanyi ont publié en 1931 l&#039;article On Simple Gas Reactions dans lequel ils décrivent les trajets des atomes dans la réaction  + H --&gt; H +  (échange d&#039;atomes). Ces travaux aboutiront au développement des notions de $E_{bond}= D_e [\exp(-2\beta(r-r_e))-2\exp(-\beta(r-r_e))]$$E_{ant}= \frac{D_e}{2} [\exp(-2\beta(r-r_e))+2\exp(-\beta(r-r_e))]$$r_e$$D_e$$\beta$$E_{bond}= \frac{Q_{AB}+\alpha_{AB}}{1+S^2_{AB}} = \frac{Q_{AB}+\alpha_{AB}}{1+k}$$E_{a…</description>
