WebEach photosynthetic pigment has a set of wavelength that it absorbs, called an absorption spectrum. Absorption spectra can be depicted by wavelength (nm) on the x-axis and the degree of light absorption on the y-axis. WebUV-Vis spectroscopy uses the ultraviolet and visible regions of the electromagnetic spectrum. Infrared spectroscopy uses the lower-energy infrared part of the spectrum. In UV-Vis spectroscopy, wavelength is usually expressed in nanometers (1 nm = 10 -9 m). The UV range normally extends from 100 to 400 nm, with the visible range from ...
