An internal coordinate Hamiltonian is presented to analyze Fermi resonances between CH stretching and HCH bending modes. The overtone spectra of CH2Br2 and CD2Br2 mols. are calculated by using 69 basis sets and available experimental data. The calculated frequencies are in agreement with the experimental Also new force field constants including fraa are obtained.
