Abstract: The INDOseries of methods were used to optimize the structures of C76n(-4≤n≤6) without any symmetry constriction. It was indicated that there are 30 kinds of bonds and 19 types of unique carbon atoms, but there are not Jahn Teller distortion in C76n, which is different from C76n and C70n .Furthermore, the C76 nions are less stable than C76. Based on the optimized geometries, the electronic spectra were calculated by INDO/SCImethod. It was shown that the NIRabsorptions for C76n singlet will appear beyond 1000 nm. Electronic transition was assigned theoretically and the reason of red shift for absorption peaks of C76n compared with those of C76 was discussed.

Key words: C76, C76n, Electronic spectra, INDO
