The infrared region of the auroral spectrum is rich in molecular and atomic emissions. The molecular bands are due to a new system of N+2, the first positive system of N2, and the atmospheric system of 02. Several permitted atomic lines of N I and 0 1, as well as Ha, are present. A table of wave lengths and intensities has been prepared.
A. B. Meinel (1951) studied this question.
