A Critical Look at Linus Pauling’s Influence on the Understanding of Chemical Bonding

open access: yesMolecules, 2021
The influence of Linus Pauling on the understanding of chemical bonding is critically examined. Pauling deserves credit for presenting a connection between the quantum theoretical description of chemical bonding and Gilbert Lewis’s classical bonding ...
