The Quantum Interference Energy Analysis: A Tutorial Introduction

In this chapter, a tutorial on the Interference Energy Analysis method is presented. Details on the input construction and interpretation of the results are shown. The examples cover the energy partitioning of the N2 molecule considering different group splitting schemes, the role of quantum interference and quasi-classical effects on the ground-state potential energy curve of the OH radical, and the analysis of the π orbitals of the s-trans-1,3-butadiene molecule.
