A modification of
canonical variational transition-state theory in which, for energies below the
threshold energy, the position of the
dividing surface is taken to be that of the microcanonical
threshold energy. This forces the contributions to
rate constants to be zero below the
threshold energy. A compromise
dividing surface is then chosen so as to minimize the contributions to the
rate constant made by reactants having higher energies.
