Model of organic reactivity that generates a reaction profile from curves that describe the energies of reactant, product, and intermediate electronic configurations (or, alternatively, reactant, product and intermediate electronic states) as a function of the reaction coordinate
. The crossing reflects the electronic reorganization that accompanies the transformation
of reactants and products.
