Abstract
New spectrographic observations in the vacuum‐ultraviolet region of the pink nitrogen afterglow are reported. Nitrogen bands representing 13 ev of energy, N I lines of 10.6 ev energy, and, upon the addition of Hg, Hg I lines of 10.1 ev and Hg II lines of 7.5 ev were observed with the 1st positive and 2nd positive N2 bands and 1st negative N2+ bands characteristic of the pink glow. The excitation of the nitrogen bands is discussed. Quenching of the pink glow by an ac electric field is related to the excitation mechanisms producing this glow.
