| dc.description | The frequency dependence of third harmonic generation (THG) in C_{60} is calculated, making use of a tight-binding model for pi-electrons. The magnitudes of the THG, about 10^{-12} esu, near zero frequency, agree with those in experiments for the low-energy region. We can also explain the order of the magnitude, 10^{-11} esu, around the three-photon resonance peak due to the lowest allowed excitation, recently measured by Meth et al. At higher energies, we predict a large enhancement of the THG at 3 omega \sim 6eV as a result of double resonance enhancement. | |
