Dissociation of the HCN molecule in the highly excited vibrational states
高激发振动态氰化氢分子的解离研究

The bond breaking at high excitation of the HCN molecule with various couplings is studied along with Morse oscillator by the coset (phase) space method of Lie algebra. It is demonstrated that the couplings of higher orders, are prone to bond dissociation. We also note that couplings reduce the dissociation energy.
