The splitting of some solar spectral emission lines due to the presence of a strong magnetic field. Briefly, the lines split into three or more components of characteristic polarization. The components are circular if the local magnetic field is parallel to the line of sight, and linear if the field is perpendicular to the line of sight. The amount [..]

The splitting of spectral lines when an external magnetic field is applied.

A shift in the energy levels of an isolated atom or molecule as a consequence of an external magnetic field. The energy levels of an atom (or molecule) depend on the internal forces that electrons and [..]

The splitting of atomic energy levels into two or more sublevels by means of a magnetic field as seen in spectral lines under these conditions.

A change in wavelength of emitted light when the source of light is placed in a magnetic field.

Is the split of an spectral line into several components in the presence of a magnetic field. In most atoms, there exists several electronic configurations that have the same energy, so that transitions between different pairs of configurations correspond to a single line. Named after the Dutch physicist Pieter Zeeman. [more]

The splitting of the frequency of light emitted by atoms, when the emission occurs in a strong magnetic field, into two or more closely spaced frequencies. The Zeeman effect of light from sunspots gav [..]
