Description UV/VIS spectroscopy implies absorption/reflection measurements carried out in the ultraviolet and visible light spectrum. According to the Beer-Lambert law, which links the attenuation of light to the characteristics of the material through which the light passes, a sample’s absorbance is directly proportional to the concentration of the absorbing specimen. This technique is extensively used in research and analytical laboratories for the quantitative and qualitative analysis of all molecules and specific compounds that absorb ultraviolet and visible electromagnetic radiation. UV-Visible technique can be employed in impurity detection of compounds, concentration measurements, structure elucidation of organic compounds, studying chemical kinetics, and detection of functional groups etc.
