Vibration--vibration energy exchange processes in the collision systems H/sup 35/Cl(1)+H/sup 37/Cl(1), H/sup 35/Cl(1)+H/sup 35/Cl(1), and H/sup 37/Cl(1)+H/sup 37/Cl(1) have been investigated over the temperature range 100--1000 /sup 0/K based on a long-lived collision model. It is found that the isotopic energy exchange process H/sup 35/Cl(1)+H/sup 37/Cl(1)..-->..H/sup 35/Cl(2)+H/sup 37/Cl(0) is the most efficient, whereas the production of H/sup 37/Cl(2) from the same initial state is the least efficient. A negative dependence of energy exchange probability on temperature is found for all four processes over the temperature range.
