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 4fz–4fz-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).
