Abstract

Second-order hyperpolarizibilities γ of the buckminsterfullerenes C₇₀ at three different wavelengths were determined by third-harmonic generation in a toluene solution and compared with those of C₆₀. Strong effects with γexceeding 5 × 10⁻³² esu were observed in the three-photon resonant regime. The nonresonant measurements indicate a negative real hyperpolarizibility in C₇₀ and a positive γ for C₆₀, both of the order of 10⁻³³ esu.
