Description
The ultraviolet-visible portion of the electromagnetic spectrum that is most commonly studied covers the wavelength range from 200 to 700 nm. The energy of this wavelength range of light causes electronic transitions in molecules and depends on whether transitions involve nonbonding or bonding (π or π*) electrons. The position of absorption of the radiation depends on the degree of conjugation and the nature of substituents on the molecules. In conservation science, this technique is most useful for the identification of dyestuffs through solution spectroscopy.
