THE EMISSION SPECTRUM OF ALUMINUM MONOFLUORIDE I

Abstract

Two band systems of the emission spectrum of AlF are described, viz. the far ultraviolet A1Π − X1Σ system discovered by Rochester in absorption, and a new system due to a 1Σ − A1Π transition in the region 8175 Å–6670 Å. A revised vibrational analysis of the A1Π − X1Σ system is given as well as the vibrational and rotational analyses of the new system, which is the C1Σ − A1Π system of AlF.
