Paper Abstract

The vibrational kinetics of nitrogen in a shock wave was studied with use of broadband CARS. We compared the results of our own calibration tests of time relaxation of pure nitrogen with those obtained by other authors. The conclusion was made that this method (CARS) is adequate in studying of relaxation phenomena of the molecules in shock waves. The rates of a VV' exchange in mixtures N2-O2 was measured. We estimate the lower bound for the time of de-excitation of energy exchange between molecules and atoms of nitrogen.
