The efficiency of gas/wall vibrational energy transfer has been studied over the temperature range 800-1100 K by the "variable encounter" method. The average energies transferred per deactiviting collisions with the wall were determined at 800 K to be 3200 cm-1 and 2900 cm-1 for the 1,1,2,2-tetrafluorocyclobutane (TFCB) and 1-methyl-2,2,3,3-tetrafluorocyclobutane (MTFCB) molecules, respectively. This energy increased strongly with decreasing temperature. A comparison is made of <ΔE′> with previous results for related molecules.
