  Pieter Zeeman
Pieter Zeeman (Zonnemaire (Schouwen-Duiveland), Netherlands, May 25, 1865 – Amsterdam, October 9, 1943) was a Dutch physicist who shared the 1902 Nobel Prize in Physics with Hendrik Lorentz for his discovery of the Zeeman effect.
Pieter Zeeman was born in Zonnemaire, a small town on the island of Schouwen-Duiveland, Netherlands to Catharinus Forandinus Zeeman, a minister of the Dutch Reformed Church, and Willemina Worst.
Zeeman, then a student of the highschool in Zierikzee, made a drawing and description of the phenomenon and submitted that to Nature, where it was published.

 Zeeman Effect
First observed by Pieter Zeeman, this splitting is attributed to the interaction between the magnetic field and the magnetic dipole moment associated with the orbital angular momentum.
The Zeeman effect for the hydrogen atom offered experimental support for the quantization of angular momentum which arose from the solution of the Schrodinger equation.
While the Zeeman effect in some atoms (e.g., hydrogen) showed the expected equally-spaced triplet, in other atoms the magnetic field split the lines into four, six, or even more lines and some triplets showed wider spacings than expected.

In the so-called normal Zeeman effect, the spectral line corresponding to the original frequency of the light (in the absence of the magnetic field) appears with two other lines arranged symmetrically on either side of the original line.
In the anomalous Zeeman effect (which is actually more common than the normal effect), several lines appear, forming a complex pattern.
Since the separation of the components of the spectral line is proportional to the field strength, the Zeeman effect is particularly useful where the magnetic field cannot be measured by more direct methods.

For the normal Zeeman effect on the Cd red line, perpendicular to B, we measured the splitting 2s as a function of voltage applied to the magnet coils over a range from 4 V to 12 V, in steps of 1 V. We observed the polarization of the displaced lines and the undisplaced line.

 Pieter Zeeman
Zeeman, who had been a student of Lorentz at the University of Leiden, began lecturing at Leiden in 1890.
Six years later, at the suggestion of Lorentz, he investigated the effect of magnetic fields on a source of light and found that each of the lines in the spectrum of emitted light split into several lines; this became known as the Zeeman effect.
Zeeman was appointed professor of physics at the University of Amsterdam in 1900 and director of its Physical Institute in 1908.

 Zeeman effect
Also known as Zeeman splitting, the broadening or splitting of a spectral line into several polarized components when the source is in a strong magnetic field; it is named after the Dutch physicist Pieter Zeeman (1865-1943).
Because the amount of Zeeman splitting and of polarization depend on the magnetic field strength, this effect provides a power tool for investigating cosmic magnetic fields.

 Doppler Shift and Zeeman Effect Spectroscopy
We would expect, for example, that the Zeeman effect which you studied in a previous experiment should be visible in at least some of the solar absorption lines.
For the Zeeman effect measurements, the 16 in telescope must be used.
Even with a multichannel detector, this would tend to reduce the apparent Zeeman splitting or broadening; since your data acquisition scheme involves scanning through the spectrum, this means your spectra will be subject to a non-uniform spectrum normalization, again because the sunspot light is so much less intense than that of the surrounding region.

 The Zeeman Effect
The Zeeman effect can be interpreted in terms of the precession of the orbital angular momentum vector in the magnetic field, similar to the precession of the axis of a spinning top in a gravitational field.
For example, polarizing sunglasses are often effective in suppressing ambiant glare because light reflected from surfaces has a particular polarization and polarizing sunglasses are designed to not pass that polarization of light.
One practical example in astronomy of such polarization effects is that in the preceding example the middle transition is polarized such that it cannot be easily be obverved from directly over a surface perpendicular to the magnetic field.

Including hyperfine structure with the Zeeman effect is more difficult, since the field associated with the proton magnetic dipole moment is weak, and hence it does not take a particularly strong external field to make the Zeeman effect comparable in magnitude to the strength of the hyperfine interactions.
