The magnetic cleavage of the spectral lines is dependent on the size of the charge of the electron, or, more accurately, on…

The rotation of the polarization plane is extraordinarily small in all gases, thus also in sodium vapour.

According to well-known electrodynamic laws, an electron moving in a magnetic field is acted upon by a force which runs perpendicular to…

I should point out, however, that at first some difficulty was experienced in observing the phenomena predicted by the theory, owing to…

Moreover, photography has made it possible to fix these images and now provides us with a permanent record of each observed spectrum,…

It was not simply out of a spirit of contradiction that I exposed a light source to magnetic forces. The idea came…

In the absence of a magnetic field the period of all these oscillations is the same. But as soon as the electron…

We studied the light source in the direction of the magnetic force, we perforated the poles of the magnet; but even in…

Nature gives us all, including Prof. Lorentz, surprises. It was very quickly found that there are many exceptions to the rule of…

I count myself fortunate to be able to contribute to this work; and the great interest which the Royal Swedish Academy of…

Now all oscillatory movements of such an electron can be conceived of as being split up into force, and two circular oscillations…

— Pieter Zeeman

Now if this electron is displaced from its equilibrium position, a force that is directly proportional to the displacement restores it like…

On the basis of Lorentz's theory, if we limit ourselves to a single spectral line, it suffices to assume that each atom…

Had we really succeeded therefore in altering the period of vibration, which Maxwell, as I have just noted, held to be impossible?…
