At low energies, molecular vibrational motion is described by the normal modes model. This
model breaks down at higher energy, with strong coupling between normal modes and …

A theory of approximate dynamical constants of motion is presented for vibrational (and
implicitly, rovibrational) spectra of polyatomics with multiple nonlinear resonances. The …

The paper describes methods and fast computational algorithm for building effective
Hamiltonians in molecular physics using perturbative approach. Separations of fast and …

We report results from quantum dynamical simulations of ultrafast vibrational redistribution
processes in the CH chromophore of CHX3 molecules (CHD3, CHF3) during and after …

Canonical Van Vleck perturbation theory (CVPT) is used to investigate rotation–vibration
mixing of highly excited vibrational states of SO2 and H2CO. For SO2 we find a nearly …

Techniques of quantum, semiclassical, and nonlinear classical mechanics are employed to
investigate the bending dynamics of acetylene, as represented by a recently reported …

In contrast to the traditional analysis of molecules using local mode behavior, where the
degree of locality is given through a function in terms of Morse potential parameters, new …

The vibrational motion of highly excited molecules is discussed in terms of exact quantum
and classical mechanics calculations, employing global potential energy surfaces, as well …
