A New Nitrogen Afterglow Spectrum

Subjects

Abstract

IN a communication in these columns1 I directed attention to the presence of two members of the Vegard-Kaplan system of nitrogen in the spectrum of the afterglow that was discovered by me in 19342. Although very weak, the presence of these bands was the first direct proof of the existence of meta-stable molecules in active nitrogen. The spectrum of this afterglow was a very faithful reproduction of the auroral spectrum.
