Main Page | See live article | Alphabetical index Stark spectroscopy or electroabsorption spectroscopy is a form of UV/Vis spectroscopy, albeit that 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. See also: Stark effect This article is from Wikipedia. All text is available under the terms of the GNU Free Documentation License.
