We review a theory for coupled many-nonlinear oscillator systems that describes quantum
ergodicity and energy flow in molecules. The theory exploits the isomorphism between …

The use of geometric methods in classical mechanics has proven fruitful, with wide
applications in physics and engineering. In this book, Professor Marsden concentrates on …

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

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

The efficiency and insight of global, polyad-based modeling in overtone spectroscopy and
dynamics is demonstrated. Both vibration and vibration–rotation polyads are considered …

Out-of-time-order correlators (OTOCs) can be used to probe how quickly a quantum system
scrambles information when the initial conditions of the dynamics are changed. In sufficiently …

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 …

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 …

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 …

Catastrophe theory is used to classify the dynamics of spectra of resonantly coupled
vibrations, based on earlier work on the bifurcation structure of the Darling–Dennison and 2 …
