Zeeman's studies showed that atomic spectral lines split into multiple components when the atoms were excited in the presence of an external magnetic field. Furthermore, for field strengths less than a Tesla, the magnitude of the splitting was proportional to the strength of the field. The semi-classical theory of the atom at that time could predict only the splitti…
