TL;DR: In this paper, the second hyperpolarizability of singlet diradical systems is investigated using a model compound, the p-quinodimethane (PQM) molecule with different both-end carbon−carbon (C−C) bond lengths, by several ab initio molecular orbital and density functional theory methods.

Relationship between third-order nonlinear optical properties and magnetic interactions in open-shell systems: a new paradigm for nonlinear optics.
Masayoshi Nakano,Ryohei Kishi,Suguru Ohta,Hideaki Takahashi,Takashi Kubo,Kenji Kamada,Koji Ohta,Edith Botek,Benoît Champagne +8 more
TL;DR: This Letter theoretically shows that the third-order NLO properties are drastically enhanced in symmetric open-shell diradical systems with intermediate Diradical character and further reveals that this enhancement is associated with the ferromagnetic and antiferromagnetic interactions.
