Abstract

So long ago as 1934, we observed, in the night sky spectrum, radiations characteristic of the nuclei of the comets, at about λ λ 4300 and 4050 A. 1. Their origin was then unknown. The recent identification2 of cometary radiations near λ 4300 with a band of the CH molecule induced us to search systematically for the CH bands in the sky spectrum. For this purpose we used unpublished tables of wave-lengths measured by Gauzit in the ultra-violet and by Cabannes and Dufay in the blue and violet regions of the visible spectrum.
