A development of
transition-state theory in which the
dividing surface is varied so as to minimize the rate calculated for a fixed energy. The rate expressions
obtained in a microcanonical treatment can be integrated over the energy, taking into
account the statistical distribution over energy states, so as to give the canonical,
or thermal, rates.
