Abstract
THE vibrational relaxation rate of certain diatomic molecules seems to be faster in expansion flows than in excitation conditions behind shock fronts. For Φ, the ratio of the vibrational relaxation time behind a shock wave to the relaxation time in an expansion, values of 1 (ref. 1), 5 (ref. 2), and 100–1,000 (ref. 3) have been reported for the relaxation of CO in supersonic expansions.
