Stark spectroscopy (chemistry)

In chemistry, Stark spectroscopy or electroabsorption spectroscopy is a form of spectroscopy (usually, UV/Vis spectroscopy), where the sample is exposed to a strong electrical field. This induces small changes in the energy of the electronic levels of the material under investigation and thus small differences in the absorption spectrum.

The technique is named after Johannes Stark.
