Structure of Line Spectra in Crystals

Abstract

NEW investigations of the spectra of chromium in crystals¹ have rendered very probable the surmise expressed by Saha² as to how these spectra originate. The possibility is thus afforded of enlarging the explanation proposed previously³ resulting in the main characteristics for a transition of an electron and its change through the crystal lattice, inasmuch as now also the laws of the various transitions of electrons for the spectra of phosphorescence of the rare earths can be investigated. The explanation of transitions 4f^z–4f^z-1 5d offered by Laporte⁴ should come into consideration only for the diffuse spectra of the rare earths, for example, of neodymium (also of samarium⁵).
