WebSpectrophotometry is a procedure for determining how much light is reflected by a chemical material by measuring the strength of light as a light beam travels through the sample solution. The fundamental theory is that light is absorbed or emitted over a certain wavelength spectrum by each compound. WebAug 10, 2024 · A spectrofluorometer is equipped with two scanning monochromoators permitting variation in excitation wavelength, the emission wavelength or both (constant …
