Preferred Label : attractive potential-energy surface;
IUPAC definition : A potential-energy (reaction) surface for a process strong A B–C /strong in which
the initial descent of the system into the product valley is associated with a substantial
decrease in the strong A–B /strong distance and with little separation between the
products strong A–B /strong and strong C /strong . In terms of a potential-energy
profile, the energy barrier occurs in the early stage of the reaction path. Attractive
surfaces are also called early-downhill surfaces, and the barrier in such a surface
is called a Type-I barrier.;
