Abstract

The $C_{2}N_{2}+N_{2}O$ flame is a remarkable source. It is very rich in molecular emissions. The entire visible and ultraviolet regions show well developed electronic bands of the CN, NO and $C_{2}$ molecules. The source, being intense, can be used very successfully with high resolution spectrographs. The emissions in the infrared region are particularly unique. We have not observed any continuum in the infrared. An intense emission was recorded with a grating in the region 4-5 microns. About 400 rotational lines have been measured in this infrared band. A discussion will be presented of all the electronic and infrared emission bands observed with this source.
