Spectroscopic Analysis of Azide Decomposition Products for Use in a Pyrotechnically Initiated Carbon Dioxide Chemical Laser,

摘要

In the consideration of Sodium azide as a potential nitrogen source for a nitrogen-carbon dioxide chemical laser,it is important to know the fraction of the heat of decomposition of the azide that will appear as vibrational excitation in the nitrogen. To this end,the progressions of the Lyman-Birge-Hopfield bands of nitrogen were monitored by means of absorption spectroscopy in the vacuum ultraviolet,upon thermal decomposition of sodium azide. The experimental system is described and results to date are discussed. (Modified author abstract)
