Pauli gives consideration to a theoretical treatment of the Zeeman effect which includes relativistic terms.

Pauli writes about the g-values of neutral and ionized atoms.

Pauli replies to Landé's question about a possible dicontinuity in the behavior of free and very loosely bound electrons.

Pauli gives a detailed account of his ideas about the anomalous Zeeman effect and the resulting consequences for the building of the electronic shell.

Pauli writes about the respective merits of the "inclination" theory and the relativistic theory of multiplets. He asks questions concerning certain transitions in alkali-spectra and the spectrum of Pb, anticipating Pauli's exclusion-principle.

Pauli says to Landé that he has sent off his paper for publication.

Pauli thanks Landé for sending him Back's and Landé's papers. He explains theoretically the line intensities in the partial Paschen-Back effect.

Pauli is enthusiastic about Landé's recent paper and the assumption that the optical doublets and X-ray doublets are in principal the same phenomenon.

Pauli writes about his calculations of the Balmerline intensities with the help of Schrödinger's calculus.

Pauli's interpretation of intercombination lines and the application of his model to several cases (Zeeman-effect). He expresses hope for the progress of physics through Heisenberg's mechanics.
