2. Ultraviolet–visible spectroscopy - Wikipedia

   en.wikipedia.org/wiki/Ultraviolet–visible...

   UV-Vis spectroscopy is routinely used in analytical chemistry for the quantitative determination of diverse analytes or sample, such as transition metal ions, highly conjugated organic compounds, and biological macromolecules. Spectroscopic analysis is commonly carried out in solutions but solids and gases may also be studied.

3. UV-Vis absorption spectroelectrochemistry - Wikipedia

   en.wikipedia.org/wiki/UV-Vis_absorption_spectro...

   A specific source is required for the UV-Vis spectral region, being the most common the deuterium/halogen lamp. Spectrometer: instrument that allows measuring the properties of the light in a certain region of the electromagnetic spectrum. It uses a monochromator to separate the different spectral wavelengths of interest emitted by the light ...

4. Ultraviolet–visible spectroscopy of stereoisomers - Wikipedia

   en.wikipedia.org/wiki/Ultraviolet–visible...

   Ultraviolet–visible spectroscopy (UV–vis) can distinguish between enantiomers by showing a distinct Cotton effect for each isomer. UV–vis spectroscopy sees only chromophores, so other molecules must be prepared for analysis by chemical addition of a chromophore such as anthracene.

5. Spectrophotometry - Wikipedia

   en.wikipedia.org/wiki/Spectrophotometry

   Ultraviolet-visible (UV-vis) spectroscopy involves energy levels that excite electronic transitions. Absorption of UV-vis light excites molecules that are in ground-states to their excited-states. [5] Visible region 400–700 nm spectrophotometry is used extensively in colorimetry science. It is a known fact that it operates best at the range ...

6. Variable pathlength cell - Wikipedia

   en.wikipedia.org/wiki/Variable_pathlength_cell

   In ultraviolet-visible spectroscopy or spectroscopy in general a 1 cm pathlength cuvette is used to measure samples. The cuvette is filled with sample, light is passed through the sample and intensity readings are taken. The slope spectroscopy technique can be applied using the same methods as in absorption spectroscopy.

7. Spectroelectrochemistry - Wikipedia

   en.wikipedia.org/wiki/Spectroelectrochemistry

   Ultraviolet-visible absorption spectroelectrochemistry is a technique that studies the absorption of electromagnetic radiation in the UV-Vis regions of the spectrum, providing molecular information related to the electronic levels of molecules. [10] It provides qualitative as well as quantitative information.
