Influence of temperature on the quenching of active nitrogen at various pressures

  • S. S. Joshi

Effect of heating active nitrogen has been investigated at various streaming pressures in the range 15 to 33 mm. Hg by observation of its after-glow visually and excitation of the iodine luminiscence. It is found, it would appear for the first time in this field of research that the quenching of the after-glow is produced at a well-defined temperature, which increases with increase of the gas pressure. Existence of a glowless but chemically active form of nitrogen is considered improbable.
