Overall, we have used the differnece density function to develop a chemically appealing interpretation of the DA reaction between cyclopentadiene and acrylonitrile. While this reaction was previously explored with the high-level scQED-CCSD approach, we have extended this work to incorporate a relavent chemical explanation in terms of the cavity-mediated redistribution of inter-and intramolecular bonding orbitals by examing the polaritonic ground state density. These orbitals are explicitly modified by the cavity to facilitate the formation (or destruction) of the intermolecular bond by donating electron density from intramolecular π-orbitals (largely localized on the cyclopentadiene species) to the forming intermolecular bond.
