Abstract
The second hyperpolarizabilities (γ) for three spin states (doublet, quartet and sextet) of Ï-conjugated molecules with a charged defect are investigated as a model of novel spin- and charge- modulated nonlinear optical systems. It turns out from the UCCSD(T) results that a charged defect makes the Î³Ë negative in sign for low and intermediate spin states (doublet and quartet) while the highest spin, sextet, state exhibits remarkably enhanced positive γ value.
