The first edition, by PR Bunker, published in 1979, remains the sole textbook that explains
the use of the molecular symmetry group in understanding high resolution molecular …

▪ Abstract We review stimulated emission pumping as used to study molecular dynamics.
The review presents unimolecular as well as scattering studies. Topics include …

Controlling chemical reactions by selecting specific bond or vibrational mode excited states
of the reactants and analyzing the energy disposal into specific vibrational states as well as …

Resonances are ubiquitous in dynamical systems with many degrees of freedom. They have
the basic effect of introducing slow-fast behavior in an evolutionary system which, coupled …

Intramolecular vibrational energy redistribution (IVR) impacts the dynamics of reactions in a
profound way. Theoretical and experimental studies are increasingly indicating that …

An approach for identifying resonances in vibrational perturbation theory calculations is
introduced. This approach makes use of the corrections to the wave functions that are …

The second-order vibrational Hamiltonian of a semi-rigid polyatomic molecule when
resonances are present can be reduced to a quasi-diagonal form using second-order …

This article reviews recent research on acetylene which is intended as a contribution to the
understanding of intramolecular vibrational energy flow when it is poorly described by either …

Anharmonic vibrational states of semirigid polyatomic molecules are often studied using the
second-order vibrational perturbation theory (VPT2). For efficient higher-order analysis, an …

We have gathered 122 known experimental data concerning the vibrational energy levels of
acetylene, C2H2, up to 12 000 cm 1. We have fitted the data simultaneously to a model …
