UV Visible Spectroscopy

Spectroscopy refers to the absorption or emission of light or other radiations by matter. When a substance or chemical absorbs light or radiation, they reach an excited state followed by de-excitation or emission of the light or radiation forming distinct spectra. UV-visible spectroscopy or ultraviolet-visible refers to the absorption and emission in the ultraviolet and visible regions of the electromagnetic spectrum.

Question

Definition Definition Organic compounds with a planar cyclic ring of atoms bonded through alternated single and double bonds. Aromatic organic compounds, also called arenes, are an important class of hydrocarbons under the branch of organic chemistry.
