one source date December 2010 Stark spectroscopy sometimes known as electroabsorption emission spectroscopy is a form of spectroscopy based on the Stark effect . In brief, this technique makes use of the Stark effect or electrochromism either to reveal information about the physiochemical or physical properties of a sample using a well characterized electric field or to reveal information about an electric field using a reference sample with a well characterized Stark effect. The use of the term Stark effect differs between the disciplines of chemistry and physics. Physicists tend to use the more classical definition of the term see Stark effect , while chemists usually use the term to refer to what is technically electrochromism . ref Liptay, W. Berichte der Bunsengesellschaft f r physikalische Chemie . 1974 , 80, 207 217. Liptay, W. Excited States . 129 159. ref In the former case, the applied electric field splits the atomic energy levels and is the electric field analog of the Zeeman effect . However, in the latter case, the applied electric field changes the molar absorption coefficient of the sample, which can be measured using traditional absorption or emission spectroscopic methods. This effect is known as electrochromism. See also Stark effect Plasma diagnostics References references DEFAULTSORT Stark Spectroscopy Category Spectroscopy ... more details

Unreferenced date December 2009 Inappropriate tone date December 2007 Force spectroscopy is a dynamic analytical technique that allows the study of the mechanical properties of single polymer molecule s or proteins , or individual chemical bond s. It is performed by pulling on the system under scrutiny with controlled forces. As a single molecule technique, as opposed to typical statistical ensemble ensemble spectroscopies, it allows a researcher to determine properties of the particular molecule under study. In particular, rare events such as conformational change, which are masked in an ensemble, may be observed. The name force spectroscopy , although widely used in the scientific community, is somewhat misleading, because there is no true matter radiation interaction . Force spectroscopy measures the behaviour of a molecule under stretching or torsional mechanical force .

Fluorescence spectroscopy aka fluorometry or spectrofluorometry, is a type of electromagnetic spectroscopy which analyzes fluorescence from a sample.

A complementary technique is absorption spectroscopy . Devices that measure fluorescence are called fluorometer s or fluorimeters.

Unreferenced date December 2009 Orphan date February 2009 Stereoscopic spectroscopy is a type of imaging spectroscopy that can extract a few spectral parameters over a complete image plane simultaneously. A stereoscopic spectrograph is similar to a normal spectrograph except that A it has no slit, and B multiple spectral order s often including the non dispersion dispersed zero order are collected simultaneously. The individual images are blurred by the spectral information present in the original data. The images are recombined using stereoscopy stereoscopic algorithm s similar to those used to find ground feature altitudes from parallax in aerial photography . Stereoscopic spectroscopy is a special case of the more general field of tomographic spectroscopy . Both types of imaging use an analogy between the math x,y, lambda math data space of imaging spectrographs and the conventional math x,y,z math 3 space of the physical world. Each spectral order in the instrument produces an image plane analogous to the view from a camera with a particular look angle through the math x,y, lambda math data space, and recombining the views allows recovery of some aspects of the spectrum at every location in the image.
