He was an important figure in the use of quantum mechanics to describe chemical valency, molecular orbitals, bond order, and the electronic structure of molecules.<br /> <br /> == Quantum chemistry ==<br /> Coulson helped turn the quantum theory of chemical bonding into a practical discipline. His work connected valence bond ideas with molecular orbital calculations and helped clarify how electron distribution determines bond strength and molecular shape.<br /> <br /> In the Quantum Collection, Coulson is especially relevant to:<br /> * [[Physics:Quantum molecular orbital theory]]<br /> * [[Physics:Quantum valence bond theory]]<br /> * [[Physics:Quantum bond order]]<br /> * [[Physics:Quantum computational chemistry]]<br /> <br /> == Bonding and valency ==<br /> Coulson&#039;s textbook &#039;&#039;Valence&#039;&#039; became a widely used introduction to quantum descriptions of chemical bonding. It helped chemists move from classical bond pictures toward wave functions, electron density, resonance, and approximate molecular calculations.<br /> <br /> == See also ==<br /> * [[Biography:Linus Pauling]]<br /> * [[Biography:Robert S.
