curve-crossing model
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 @R05168@. The crossing reflects the electronic reorganization that accompanies the @T06446@ of reactants and products.
