Contributors apply the isoelectronic principle to fundamental rules for predicting molecular structure, the properties of novel inorganic compounds, the chemistry of positrons and other "elementary" particles, the energetics of "inert" gas containing species, and the design of conducting polymers and electronic devices on a molecular scale. The book includes insights as diverse as the theoretical underpinning of the Valence Shell Electron Pari Repulsion (VSEPR) theory, the design of viable helium compounds and organic conductors, and prediction of enthalpies of the formation of inorganic salts.
