The stretching and bending vibrational spectrum of a polyatomic molecule XH3 is calculated in an algebraic model, where the coupling between stretches and bends is described by Fermi resonance terms. The algebraic Hamiltonian established in terms of local creation(annihilation) operators is shown to provide good agreement with the experimental data of ammonia.
