Chromophores
• They are groups with one element of unsaturation (unsaturated linkages or groups) and cause coloring to the molecules when they are attached to a non-absorbing hydrocarbon chain.
Auxochromes
• They are groups that do not confer color but increase the coloring power of a chromophore.
• They are functional groups that have non-bonded valence electrons and show no absorption at l > 220 nm; they absorb in the far UV.
• -OH and -NH2 groups cause a red shift.
