The two-mode coupling in analogy with the motion of the pendulum is proposed by an algebraic approach, which is based on an algebraic classical Hamiltonian on the coset sphere. The analysis of the molecular highly excited vibration of H2O shows that the chaotic motion in the coset (phase) space is most probable in the levels close to the separatrix, while the regularity is dominant for the lower or higher levels.
