As presented on page 149 by Kenta Yamada and Nobuaki Koga, a method to analyze intramolecular interaction energy is applied to an analysis of the P—O bonding in phosphine oxide in conjunction with a newly developed technique to interpret change in electronic structure upon the interaction. The inside cover picture demonstrates, as a result of the analysis, electron-transfer processes in sigma and pi spaces that reorganize the electronic structure with localized three lone pair orbitals on the O atom into the genuine electronic state and that play critical roles in the P—O bond formation.
