Unified Understanding of Structure, Reactivity and Spectroscopy Within General Valence Bond Scenarios, Obtained by Transferring Techniques Developed Within Electron-Transfer Theory

Valence bond theory and electron transfer theory are both widely applied throughout Chemical Science, usually to different applications. Nevertheless, electron transfer theory is just an extensive development of one type of valence bond model. In this article, we demonstrate how electron-transfer theory can be more broadly applied to other valence-bond scenarios. This involves (1) rederivation for Morse oscillators of many key analytical expressions from electron-transfer transfer theory pertinent to harmonic oscillators, (2) renormalization of the key parameters from electron transfer theory to facilitate broad applications, and (3) development of 3 Morse-oscillator applications.
