Some Aspects of the Recent Development of Atomic Theory Limited applicability of mechanical models. The theory of multiply periodic systems: the correspondence principle. The hydrogen spectrum and the fine structure of the hydrogen lines (periodic orbit and central orbit). The structure of the series spectra: e.g., Na spectrum. Principal quantum number and penetration. General survey of the alkali spectra. Periodic table. (Vegard.)* Example. Empirical confirmation by spark spectra of the Na type. Spectra of the potassium type. Spark spectra of alkaline earths 11. Spectra of the A1 type. Principal quantum number and intensity of lines (dispersion). The correction in TI. Kuhn. Complex structure of spectra. Mechanical interpretation. Selection rules and intensity rules. (Ornstein & Burger; Heisenberg, etc.) Difficulties for 'mechanical models. 1) Anomalous Zeeman effect. Lande. The constraint. Half quantum numbers. Heisenberg, Born.** 2) X-ray spectra. Moseley-Sommerfeld-Coster. Wentzel. ** 3) Analogy between X-ray spectra and series spectra. (Lande, Millikan.) Symbolic treatment: Stoner, Pauli, Heisenberg, (the triplet spectra). Complex structure and periodic table. Hund. Final remark.
