4.4: UV-Visible Spectroscopy. Ultraviolet-visible (UV-vis) spectroscopy is used to obtain the absorbance spectra of a compound in solution or as a solid. What is actually being observed spectroscopically is the absorbance of light energy or electromagnetic radiation, which excites electrons from the ground state to the first singlet excited.

Table-top spectrophotometer Beckman IR-1 Spectrophotometer, ca. 1941 Beckman Model DB Spectrophotometer (a double beam model), 1960 Hand-held spectrophotometer used in graphic industry. Spectrophotometry is a branch of electromagnetic spectroscopy concerned with the quantitative measurement of the reflection or transmission properties of a material as a function of wavelength.
UVVis spectrophotometer EMC18SUV EMCLAB Instruments GmbH singlebeam / absorption
A UV-Vis spectrophotometer is used to determine the absorption of light from a sample and can be used as a detector for HPLC. A sample is placed in the UV/VIS beam and absorbance versus wavelength is measured. A single beam spectrophotometer utilizes one beam of light that passes through the sample and the intensity of the light reflected from.
