摘要：

The harmonic frequencies, IR intensities and the potential energy distribution of the vibrational modes of the dioxo tautomer of uracil are calculated at the Hartree-Fock 6-31G** level. The use of a common scale factor of 0.9 results in excellent agreement between calculated and observed frequencies except for the C = O stretching modes. The use of a potential energy decomposition scheme is shown to allow a comparison with the atomic character of the modes that are inferred from experiment.
