WebThe human eye utilizes so-called red, green, and blue (RGB) photoreceptor cells (cones with peak absorbance at 420, 534, and 564 nm), which is the basis of the human trichromatic perception of colors (Plate XIX, upper image (see in the color plate section between pages 326 and 327)).Artificial sensing systems, as well as colored image display systems such … 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.
