What is UV/Vis spectroscopy?

Electromagnetic radiation in the ultraviolet and visible region of the spectrum (40 to 1000 THz) is higher in frequency (and thus energy) than that in either the microwave or infrared. This makes it a good match for the larger energy-level spacing associated with transitions between electronic energy levels. UV/Vis spectroscopy can be used to study molecules in any phase; however, it is most commonly used for liquid samples.
