Abstract:

The vibrational relaxation of gaseous H2 in mixtures of H2-Kr and H2-Kr-He has been studied by the laser schlieren method in shock waves at 1350-3000K. From the results, the relaxation times for pure H2, and for H2 highly dilute in Kr or He, are given. Solutions of the master equation for the relaxation of internal energy of nonrigid rotating Morse oscillator H2 molecules support the suggestion that rotation and vibration are strongly coupled during the observed relaxation process.
