Diffcrential cross sections of thc process Na\*(3 \*P) + M(u = 0) Na(3S) + M(u') have been mcasured for several molecules: Hz, D2, Nz, 02, CO, COz, NzO, Cz H4.

In order to compute relaxation "cross sections" for moiecule-molecule cothsions it is convenient to employ a coupled angular momentum representation which dlffcrs from that geeneralIy used.
