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

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 …

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

We present a new method of frequency analysis for Hamiltonian Systems of 3 degrees of
freedom and more. The method is based on the concept of instantaneous frequency …

Key experimental and theoretical features of mass-independent fractionation (MIF) of
isotopes, also known as the η-effect, are summarized, including its difference from the exit …

Jacket illustration. CryoSEM micrograph of a freeze-fractured yeast cell. Specimen was
prepared according to Walther et al (1995) and imaged using back-scattered electrons …

Intramolecular dynamics of highly excited DCO (2A′) is studied from a classical-quantum
correspondence perspective using the effective spectroscopic Hamiltonian proposed …

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 …

Dynamical tunnelling, introduced in the molecular context, is more than two decades old and
refers to phenomena that are classically forbidden but allowed by quantum mechanics. The …
