Reactions of energetic tritium atoms with ethyl fluoride over an extensive pressure range

摘要

Recoil tritium reactions with ethyl fluoride have been studied over a pressure range of six orders of magnitude. The results show that subsequent to Thyphen;forhyphen;H substitution, the fraction of collisionally stabilized C2H4TF ranges from 0.05 at 10minus;2Torr to 0.91 in the liquid. The low pressure results indicate that 95percnt; of the C2H4TF molecules being formed possess an excitation energy of 65 kcal molminus;1or higher. The high pressure and liquid phase studies suggest that about 15percnt; of the excited molecules have energies distributed in a very long and narrow tail at the high energy end.
