The evaluation of nonlinear optical constants (d) using second-harmonic generation (SHG) is an effective method for characterizing ferroelectric nematic liquid crystals; however, the reason why the d₁₅ component is observed only in certain molecules remained unclear. In this study, we investigated the material dependence of DIO/EST-based mixed liquid crystals and succeeded in extracting the previously buried d₁₅ and d₃₁ components by using polarization-resolved SHG. While d₁₅ did not depend on the material composition ratio, d₃₃ increased significantly with an increase in the EST ratio. We found that the apparent absence of d₁₅ in certain systems is caused by masking by the massive d₃₃ component.
