Questions & Step-by-Step Solutions

In UV-Vis spectroscopy, what does a higher molar absorptivity indicate?
  • Step 1: Understand what molar absorptivity means. It is a measure of how well a substance can absorb light at a specific wavelength.
  • Step 2: Recognize that a higher value of molar absorptivity means the substance can absorb more light.
  • Step 3: Conclude that if a substance has a higher molar absorptivity, it is more efficient at absorbing light.
