WebSTEP1: Open the absorption graph of the material, which is obtained from the UV Vis spectroscopy. STEP2: Now zoom on the area for which you want to calculate the … WebPeaks in UV spectra tend to be quite broad, often spanning well over 20 nm at half-maximal height. Typically, there are two things that we look for and record from a UV-Vis spectrum.. The first is λmax, which is the wavelength at maximal light absorbance. As you can see, NAD + has λmax, = 260 nm. We also want to record how much light is ...
