Résumé

We investigate the static second hyperpolarizabilities ( ) of singlet diradical molecules, i.e., 1,4-bis-(imidazole-2-ylidene)-cyclohexa-2,5-diene (BI2Y) and related molecule (BI2YN), by the ab initio molecular orbital and hybrid density functional theory calculations. It is found that the value of BI2Y with intermediate diradical character is about one-order as large as that of BI2YN with very small diradical character.
