▪ Abstract In this overview we discuss the vibrational spectrum of phosphaethyne, HCP, in its
electronic ground state, as revealed by complementary experimental and theoretical …

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 …

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 …

An algebraic scheme for describing nonrigid polyatomic molecules is introduced and used
to characterize bending motion in 'floppy'triatomic/tetratomic species. The salient features of …

The experimental and theoretical evidence suggests that vibrational wave functions at high
energy or in large molecules are not mixed to the maximum extent possible. One …

In this paper we study the classical and quantum mechanics of the 3-mode Baggot
vibrational Hamiltonian for H 2 O. Our aim is to classify and assign highly-excited quantum …

The bifurcation structure is investigated for a Hamiltonian for the three coupled nonlinear
vibrations of a highly excited triatomic molecule. The starting point is a quantum Hamiltonian …

The bending dynamics of acetylene are analyzed starting from spectroscopic fitting
Hamiltonians used to fit experimental spectra. The possibility is considered of a …
