Nonlinear optical properties in open‐shell molecular systems
TL;DR: The fundamental mechanism of the y–γ correlation has been explained by using a simple two‐site model and the valence configuration interaction method, and several molecular design guidelines for controlling γ have been proposed, which open a new path toward understanding the structure—NLO property relationships and toward realizing a new class of highly efficient NLO materials.
