Abstract : The intense infrared night-sky radiation in the region 9000 A < lambda < 11,000 A is identified with the vibration-rotation spectrum of the hydroxyl OH molecule. Sponer's molecular constants of OH are used for this identification. Herzberg's molecular constants do not lend themselves to this identification, indicating that they are less exact. First, the allowed lambda < 9000 A are identified. It is noted specifically that there is no emission of any kind in the night-sky spectrum at lambda = 8200-8270 A, where there should be a vibrational-rotational band of OH (10-5). This suggests that in the upper atmosphere the OH molecules are excited only to the 9-th vibrational level.
