    "abstract": "A Fermi resonance-algebraic model is proposed for molecular vibrations, where\na U(2) algebra is used for describing the vibrations of each bond, and Fermi\nresonances between stretching and bending modes are taken into account. The\nmodel for a bent molecule XY_2 and a molecule XY_3 is successfully applied to\nfit the recently observed vibrational spectrum of the water molecule and arsine\n(AsH_3), respectively, and results are compared with those of other models.\nCalculations show that algebraic approaches can be used as an effective method\nfor describing molecular vibrations with small standard deviations.",
