Energy transfer at high temperatures in the cyclopropane VEM system. Temperature dependence of delta E prime

The study of collisional energy transfer between cyclopropane molecules and a seasoned silica wall by the Variable Encounter Method has been extended upward in temperature to 1325 K. The value of (delta epsilon) the average energy of a down transition upon collision of the substrate with the wall continues to decrease monotonically. The data provide the most accurate and well documented display of the temperature trend of (delta epsilon) presently available.
