Das Emissionsspektrum der stillen elektrischen Entladung in Ammoniak-und Hydrazin-Dampf / The Emission Spectrum of the Silent Electric Discharge in the Vapours of Ammonia and Hydrazine

Below 5000 Å the silent electric discharge in ammonia essentially reveals the same emission spectrum as the glow discharge. Between 5000 and 8000 Å in discharges in NH as well as in N there appear besides the Schuster band and the Ha line especially 3 new diffuse peaks with maxima of intensity at about 5253, 6380 and 7560 Å. These emissions are caused presumably by a more than 2atomic molecule (NH , N , N or N ). The behaviour of the intensities of the H line and the Schuster band favours the hypothesis H + N → N * → N + h v for the formation of the Schuster band already put forward some time ago.
