The classical structure underlying the quantum mechanics of molecular vibrations is illustrated by reference to changes in vibrational energy distributions induced by increased anharmonic coupling as the energy increases. Specific applications to Fermi resonance models and to the level structures ar
We construct and discusss explicitly time dependent integrals of the motion of non-autonornous quantum systems. Such integrals may exist even when the classical limit of the dynamics is nonintegrable.
Ž 4 . Numerical experiments with a nonlinear x oscillator which has its harmonic frequency changing randomly with time reveal certain interesting features of its dynamics of quantum evolution. When s 0, the level populations are seen to oscillate. But, as the Ž . nonlinear coupling is switched on )
