    • It is well-known that the present DFT methods with conventional exchange-conventional functional have the significant drawbacks that γ values are overestimated with increasing the size of π-conjugated systems.41 Recently, the DFT method with a long-range correlation (LC) has been proposed to avoid such drawbacks. We therefore evaluate the γ values of IDPL, the same size phenalenyl radical system as 1 and 2, using the BLYP method with LC (LC-BLYP).42-44 It turns out that the γ value of IDPL at the LC-BLYP/6-31G* level of approximation is 1902 × 103 au Judging from this result in addition to the result by the UBHandHLYP method (γ, 2383 × 103 au),24a we predict that the overshoot of γ does not occur in the size of the system we discuss in this study
    • 24a we predict that the overshoot of γ does not occur in the size of the system we discuss in this study.
