Abstract : Velocities and velocity distributions of species in molecular beams extracted from free jets are examined theoretically and experimentally. An extension of a nearly-inviscid flow theory is successful in predicting individual species velocities. Measurements of species velocity distributions indicate the temperature of the heavy species generally exceeds that of the light. Predictions of species velocity distributions based on source flow expansion of mixtures suggest that the velocity distributions of heavy species may be narrower than previously thought. (Author)
