The central maximum is white, and the higher ... WebTypically, 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 absorbed at λmax. Here we use a unitless number called absorbance, abbreviated ‘A’.

WebAtomic absorption spectrum is the spectrum obtained when free atoms (generally gases) absorb wavelengths of light. Molecular absorption spectrum on the other hand is the spectrum that is seen when molecules of a substance absorb wavelengths of light (generally ultraviolet or visible light). WebWavelengths of light range from about 400 nm at the violet end of the spectrum to 700 nm at the red end ( see table).
