As a result, a conjugated system has a region where the p-orbitals overlap. Molecular Orbitals Many features of conjugated systems can be understood and predicted using molecular orbitals. chelsey jean shopIn theoretical chemistry, a conjugated system is a system of connected p-orbitals with delocalized electrons in a molecule, which in general lowers the overall energy of the molecule and increases stability. It is conventionally represented as having alternating single and multiple bonds. Lone pairs, radicals or carbenium ions may be part of the system, which may be cyclic, acyclic, linear or mixed. The term "conjugated" was coined in 1899 by the German chemist Johannes Thiele. flextutors glasgowkelvin.ac.uk
