Answer» olet-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. From the transmittance (T), the absorbance can be CALCULATED as A=-log (T). An absorbance spectrum is obtained that shows the absorbance of a COMPOUND at different wavelengths. The amount of absorbance at any wavelength is due to the chemical structure of the molecule.
