This short offers numerical equipment for describing and calculating invariant section area constructions, in addition to fixing the classical and quantum equations of movement for polyatomic molecules. Examples lined contain basic version platforms to reasonable situations of molecules spectroscopically studied.

Vibrationally excited and reacting molecules are nonlinear dynamical platforms, and therefore, nonlinear mechanics is the right kind concept to clarify molecular dynamics by means of investigating invariant buildings in part house. Intramolecular strength move, and the breaking and forming of a chemical bond have now chanced on a rigorous rationalization by means of learning part area structures.

2. Since x˙ is periodic in time as well as solution of the variational equations (Eq. 23), we can show that one of the eigenvalues of the monodromy matrix is equal to one. Indeed, for ζ (t) = x(t), ˙ we have ζ (0) = ζ (T ) = M(T )ζ (0) (M − I2n )ζ (0) = 0. 32) I2n is the unit matrix. The above equation is true if at least one of the eigenvalues of the monodromy matrix is equal to one. Hence, if x(t) is a periodic orbit, the variational equations have a periodic solution (x(t)), ˙ and then, one of the eigenvalues of the monodromy matrix is one.

As a matter of fact, numerically locating periodic orbits in Hamiltonian systems and continuing 46 3 Dynamical Systems Fig. 6 Projection of the spiral invariant curve from a complex unstable periodic orbit. The analytically obtained points (open squares) are compared with the numerically calculated points (filled squares), which in most of the cases, coincide [3] them in the parameter space is as science as ‘art’. In any case, finding a family of periodic obits one needs the ‘seed’ to start the process of locating the PO as well as the continuation.

At critical values of the parameters bifurcations (branching) of these invariant structures are observed, which indicate the genesis of new qualitatively different motions of the system. One of the achievements of nonlinear mechanics is the classification of elementary bifurcations, which mean bifurcations described by very simple low dimensional Hamiltonians, nevertheless, equivalently encountered in generic multidimensional dynamical systems. 1. 1 Equilibria and Elementary Bifurcations Equilibria are defined as the solutions of the equations x(t) ˙ = 0.
