Quantization Conditions, 1900-1927

Anthony Duncan, Michel Janssen

We trace the evolution of quantization conditions from Planck's introduction of a new fundamental constant (h) in his treatment of blackbody radiation in 1900 to Heisenberg's inter…

The Stark effect in the Bohr-Sommerfeld theory and in Schrödinger's wave mechanics

Anthony Duncan, Michel Janssen

The explanation of the first-order Stark effect in hydrogen by Epstein and Schwarzschild in 1916 was seen as a great success for the old quantum theory. Yet, it also revealed some…

The trouble with orbits: the Stark effect in the old and the new quantum theory

Anthony Duncan, Michel Janssen

The old quantum theory and Schrödinger's wave mechanics (and other forms of quantum mechanics) give the same results for the line splittings in the first-order Stark effect in hydr…

Kuhn Losses Regained: Van Vleck from Spectra to Susceptibilities

Charles Midwinter, Michel Janssen

We follow the trajectory of John H. Van Vleck from his 1926 Bulletin for the National Research Council (NRC) on the old quantum theory to his 1932 book, The Theory of Electric and…
