Abstract: The electronic spectra of fulleropyrrolidine derivatives were studied by using INDO/CImethods on the basis of the optimized geometrics with AM1 method. It was shown that the exception of the absorption was beyond 400 nm. The results are in good accordance with the experiment results. The nonlinear second-order optical susceptibilities βμ of the molecule were calculated according to the sum-over states(SOS) formalism. The conclusions show that these fulleropyrrolidines are good candidates with large βμ values, between -30.14×10-30 and -65.49×10-30 esu.
