摘要：

Two-photon absorption (TPA) spectra of C-60 in toluene were measured for it wide wavelength region from 270 to 680 nm by femtosecond pump-probe nondegenerate TPA spectroscopy. A distinct TPA band peaked at 314 nm was observed, and its intensity was evaluated to be 80 GM. The depolarization ratio of the TPA band was found to be zero within the experimental uncertainty, which indicates that this band is due to a totally symmetric (A(g)) two-photon allowed excited state. The energy of the observed A(g) state is about 1 eV below a prediction based on the theoretically calculated pi-electron energies. (C) 2004 Elsevier B.V. All rights reserved.
