Preferred Label : dividing surface;
IUPAC definition : A surface, usually taken to be a hyperplane, constructed at right angles to the minimum-energy
path on a potential-energy (reaction) surface. In conventional transition-state theory
it passes through the highest point on the minimum-energy path. In generalized versions
of transition-state theory the dividing surface can be at other positions; in variational
transition-state theory the position of the dividing surface is varied so as to get
a better estimate of the rate constant.;
