Abnormal changes in some lines in the spectrum of lithium

Abstract

In the course of an investigation on the flame spectra of metals, the writer has examined the spectrum of lithium. Some facts have been discovered of sufficient importance for asseparate paper. The same spectrometer was used as in the investigation on the “Spectra of Potassium, &c.” Whilst the wave-lengths of some of the lines in the flame spectrum of lithium agree closely with those given by Kayser and Runge for the lines in the arc spectrum, the wave-lengths of other lines differ considerably from these.
