Abstract：The series of INDO methods were employed to study electronic structures and spectra of fullerenes doped with nitrogen and boron CnX (n=59,69; X=N+,B-)──isoelectronic molecules of C60 and C70．It was indicated that the distortion has taken place for CnX compared with C60 and C70,and the doped fullerenes are more stable with nitrogen than with boron, meanwhile two kinds of carbon atoms near the pole of C70 are easily substituted.Electronic transition was assigned and the red-shift of spectra was discussed in this thesis.
