Ultraviolet-visible (UV-Vis) spectroscopy is one of the most popular analytical techniques because it is very versatile and able to detect nearly every molecule. With UV-Vis spectroscopy, the UV-Vis light is passed through a sample and the transmittance of light by a sample is measured. The Use of Spectrophotometry UV-Vis for the Study of ... The Use of Spectrophotometry UV-Vis for the Study of Porphyrins 89 discovered that the addition of metal salts to the reaction mixture, such as zinc acetate, increases the yield of porphyrin from 4-5% for the free-base derivative, and decreases the amount of chlorin compound. Others improvement were obtain ed by changing opportunely uv -visible spectroscopy - SlideShare Jan 19, 2016 · UV-VISIBLE Spectroscopy: Uv-vis spectroscopy is also known as electronic spectroscopy. In which the amount of light absorbed at each wavelength of Uv and visible regions of electromagnetic spectrum is measured. This absorption of electromagnetic radiations by the molecules leads to molecular excitation. 15.
