Six isomers of C24 clusters was studied by Hartree-Fock (HF), B3LYP of density functional theory (DFT) and second order perturbation theory MP2 method with basis set of 6 31G*, 6-311G*, cc-pVDZ and cc pVTZ. The geometries, vibrational frequencies, nucleus independent chemical shifts (NICS) and stabilities of the isomers were discussed. The stabilities of C24 isomers were compared. The results indicate that the order of stabilitiy for C24 isomers derived by B3LYP method at 6-311G* and cc-pVDZ level is cfbead and cbfaed, respectively, and that derived by MP2 method at 6-311G* and cc-pVDZ leve is b>c>a>e>f>d.

Key words: C24 cluster, structure, stability, harmonic frequency, nucleus independent chemical shift
