The reflection (or 'mirror') symmetry of space is among the fundamental symmetries of physics. It is connected to the conservation law for the quantum number parity and a fundamental 'non-observable' property of space (as defined by an absolute 'left

The article presents an overview of atomic and molecular tunneling processes, where tunneling of “heavy” particles (i.e., nuclei, not electrons) is important. After an introductory tour d'horizon including a brief history of the tunnel effect, we

We introduce the basic concepts of symmetry breakings and approximate constants of the motion in relation to time scales for molecular primary processes from yoctoseconds to seconds and extending to the age of the universe. We then discuss the concep

Quantum mechanical tunnelling was discovered in 1927 by Friedrich Hund in the context of a discussion of the stereomutation reaction between the enantiomers of chiral molecules. We review here the fundamental new aspects introduced by the discovery o

We report high resolution Fourier Transform Infrared (FTIR) spectra of nitrogen trifluoride (trifluoroamine, NF3) measured with the Zurich Bruker prototype spectrometer (ZP 2001) and the SLS THz/FTIR setup (2009 prototype) in the range 20–3000 cm -

From the analysis of high resolution overtone spectra it is well established that intramolecular vibrational energy redistribution (IVR) from an initially excited CH-stretching vibration is strongly influenced by its chemical environment. Due to a pr

We provide here a short review of the Latsis symposium 'Intramolecular Dynamics, Symmetry and Spectroscopy' which took place at the ETH Zürich, Hönggerberg Campus, September 6–10, 2008. The goal of the meeting was to review recent progress in spe

We report the first successful high-resolution analyses of the Fourier transform infrared (FTIR) spectrum of trisulfane. A band centered at 861.0292 cm−1 can be assigned unambiguously to the chiral trans conformer by means of ground state combinati
