UV-vis spectroscopy as an analytical tool for the characterization of polymers

Ultraviolet-Visible (UV-Vis) spectroscopy comprises electromagnetic radiation of relatively high energy, with the wavelength ranges of 200 to 400 ran, called ‘ultraviolet spectroscopy’, and 400 to 800 nm, ‘visible spectroscopy’. Both are useful for investigating the electronic structures of unsaturated molecules and for measuring the extent of their conjugation. Spectroscopic techniques always complement to each other in elucidating the structure of investigated molecules in solid, liquid or gaseous form. UV-Vis spectroscopy is one of the important analytical tools in the armory of a scientist for the characterization of polymers.
