The concentration of electrons, their temperature, and the state of nitrogen in the plasma of a vacuum arc with a titanium cathode at pressures ranging from 10/sup -3/-10/sup -1/ Pa have been measured with the aid of a spectroscopic method. It has been established that the concentration of ionized molecular nitrogen N/sub 2//sup +/ is highest at pressures equal to 6.55 x 10/sup -2/ and 2.70 Pa and that its mean kinetic energy equals 5-10 eV. The degree of vibrational excitation of nitrogen does not depend on the pressure in the range from 10/sup -2/-1 Pa. In this range of variation of the pressure, the temperature of the working gas increases from 300 to 800/sup 0/K and the electron temperature decreases from 2 to 0.3 eV.
