State-to-state energy transfer cross sections for Ax + HF (u = 2,4, and 6; J = 4.6,8, and 10) were computed using quasi-classic31 trajectories. Rotationat energy transfer is invariant with increasing u, but gyration energy transfer is signi&antiy enhanced by increasing J.

β¦ Synopsis
Emission intensities from the CO* bands at 667, 2319 and 3700 cm-' arc monitored simultaneausiy behind shock wwes over temperatures of 900 to 2300Β°K. It is confirmed that the former emission intensity changes approximaceIy exponentially but the latter two have induction periods behind shock waves. Rates and mechanisms of ener_gy transier in CO2 are discussed by comparing the esperimental data with numeric-al calculationsof the t-&.ation equations.
