conjugation

Interaction of adjacent bonds in a chemical compound having alternating single and double covalent bonds. The conjugated bonds show modified characteristics because of increased electron delocalization and sharing.

Such a conjugated system often gives rise to substances with intense colours—e.g., the biological pigments called carotenes. Another example is the carboxyl group (see carboxylic acid; functional group), in which the double bond of the carbonyl group (−C=O) is adjacent to the single bond attaching the hydroxyl group (−OH) to the carbon atom.
