Nonlinearity and Chaos in Molecular Vibrations

Nonlinearity and Chaos in Molecular Vibrations deals systematically with a Lie algebraic approach to the study of nonlinear properties of highly highly excited vibrations. The basic concepts of nonlinear dynamics such as chaos, fractals, quasiperiodicity, resonance, and the Lyapunov exponent, and their roles in the study of molecular vibrations are presented.

The 20 chapters cover the basic ideas, the concept of dynamical groups, the integrable two-mode SU (2) system, the unintegrable three-mode SU (3) system, the noncompact su (1,1) algebraic application, su (3 ) symmetry breaking and its effect asymmetric molecular rotation. Emphasis is given to: resonance and chaos, the fractal structure of eigencoefficients, the motion of acetylene, the motion of quantum numbers, one-electronic motion in multi-sites, the Lyapunov exponent, of actions function actions functionational actionsational Dational Dational Dational Dational actionsational actionsational actionsational actionsational actionsational actionsational actionsational. Dixon dip and chaos in the transitional states. This approach bridges the gap between molecular vibrational spectroscopy and nonlinear dynamics.

The book presents a framework for molecular physics, molecular spectroscopy, chemical physics and theoretical physics.
