Molecular Spectrum of Cadmium Vapour

Abstract

IN a recent article on the above subject, S. Winston Cram¹ has reported his inability to obtain, either in fluorescence or by excitation with a Tesla coil, a narrow diffuse cadmium band at 2212. He concludes that the band in that region which I obtained some years ago², using a pure electrodeless discharge in low pressure vapour, must be due to an impurity.
