Abstract: The electronic structures of ground state and electronic spectra of C60C(C≡N)2and C60(C≡N)2were calculated with INDO/2 and INDO/SCI methods. The obtained results are consistent with that of experiment in general. The nonlinear second-order optical susceptibilities βijkand βμ calculations have been performed with ZINDO-SOS method on the basis of correct electronic spectra. Analysis and discussion for the obtained results have been made. The conclusion is that the both molecules C60(C≡N)2and C60C(C≡N)2have a big β value, but C60C(C≡N)2might be expected to be one kind of nonlinear optical materials.
