WebJun 30, 2024 · Sommerfeld extended Bohr's atomic model to include orbits of varying angular momentum, where the orbits are elliptical and become gradually less eccentric as the angular momentum increases [8, 9]. He quantized the angular and radial motion separately with quantum numbers for each but, as Bucher [ 10 ] discusses at length, he … WebThe theory of Bohr must then be right.’ (cited in Pais 1991, p.154). As Pais writes, Up to that time no one had ever produced anything like it in the realm of spectroscopy, agreement between theory and experiment to five significant figures.
