Questions & Step-by-Step Solutions

In UV-Vis spectroscopy, what does a peak in the absorbance spectrum indicate?
  • Step 1: Understand that UV-Vis spectroscopy is a technique used to measure how much light a substance absorbs.
  • Step 2: Know that the absorbance spectrum is a graph that shows how much light is absorbed at different wavelengths.
  • Step 3: Recognize that a peak in this graph means that at a specific wavelength, a lot of light is being absorbed.
  • Step 4: Realize that this absorption indicates the presence of a specific ion or compound that interacts with light at that wavelength.
