The reactions of Ti8C12 with H2O and C2H4 to form Ti8C12(H2O)8 and Ti8C12(C2H4)4 were studied by using ab initio method. It was discoveered that the ligand field could induce the rearrangement of TI8c12. Our calculated results suggested in Ti8C12(H2O)8, electron transfer from H2O to Ti8C12 while in Ti8C12(C2H4)4, from Ti8C12 to C2H4 and the energy decrease and stability increasein the formation of Ti8C12(H2O)8 from Ti8C12(D2h), while the case is opposite in formation of Ti8C12(C2H4)4.

We present a theoretical study on the two-photo absorption(TPA) prperties of C60. On the basis of the equilibrium geometry optimized by B3LYP/6-31G method, we employ the ZINDO method combined SOS formula to investigate the second hyperpolarizability and TPA cross section of C60. The calculated result of the real part of the second hyperpolarizability of C6 is in good agreement with the previous calculation and the experimental observation. In the 400-1000nm range of TPA wavelength, we calculated TPA cross sections corresponding to all two photon allowed states. As a result, we find that there is only a TPA cross section maximum-995.7

ectra. calculations of the nonlinear third-order optical susceptibility (yijkl) of C70 were performed using the INDO/SDCI method combined with a sum-over-states expression The calculated value for (y)(-2w;w.w,0) is 0.882×10-33 esu (w=1.91μm), which is in good agreement with ohservation.
