Abstract

IN the course of my inquiry last year into the homology of the spectral lines of chemically-related elements I occasionally made the observation that the two strongly-marked red lines which bromine in the fluid state gives when the spark is taken from it in De la Chanal's fulgurator grow very feeble or entirely disappear in the spectrum of the rarefied vapour in the Geissler-tubes, while other lines not previously seen become visible. It appeared to me of interest to inquire more particularly into the changes of the spectrum of one and the same element, as these changes are naturally of the greatest importance in the comparison of chemically-related elements; and with this view I addressed myself to the problem of the changes of spectra at higher pressures.
