UV/Vis spectroscopy (video) Spectroscopy Khan Academy

UV–Vis spectroscopy is a very simple, rapid and low cost method with spectrophotometers available virtually at any laboratory. However, monotonic and featureless UV–Vis spectra of humic and fulvic compounds have poor resolution and provide limited information (Fig. 2).

In UV/Visible spectroscopy the UV region is considered to be any wavelength less than 340 nm. Nucleic acid, purified proteins and other organic molecules are often measured in the UV region. Another name for a UV/Vis spectrophotometer is UV/Vis spectrometer. Special cells and cuvettes have to be used in UV/Vis spectrophotometers.

Using the Spectrophotometer Michigan State University

The measurement of the band gap of materials is important in the semiconductor, nanomaterial and solar industries. This note demonstrates how the band gap of a material can be determined from its UV absorption spectrum. The term “band gap” refers to the energy difference between the top of the valence band to the bottom of the conduction band (See Figure 1); electrons are able to jump from
