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.
