The General Electric Type S-1 Lamp as a Spectroscopic Source

Abstract

The possibilities presented by the General Electric type S-1 lamp as a spectroscopic source have been investigated by employing lamps filled with argon, hydrogen, helium, neon and carbon dioxide. Nitrogen-filled lamps yielded the second positive bands of nitrogen greatly modified in form from that usually obtained from a Geissler tube discharge. The spectra of hydrogen-filled lamps which also contained mercury showed the mercury hydride bands while the spectra of carbon dioxide-filled lamps gave evidence only of the third positive bands of Deslandres. Further investigation of the more quantitative aspects of the problem will be studied.
