Abstract
A spectroscopic survey has been made over the wavelength range of 3000 Å to 9000 Å of the light from various regions of a jet of excited nitrogen flowing into an evacuated chamber. The jet of nitrogen, which was excited by a high-frequency transmitter, formed a nodular or beadlike flow pattern. Bands of the Goldstein–Kaplan, Gaydon green, and Herman infrared systems were observed in a flow boundary which surrounded a sharply defined cylindrical surface, presumably a high-density shock region.Keywords
