Gas phase mid‐infrared spectroscopy of molecular ions can nowadays be performed with
high performance mass spectrometers coupled to free electron lasers (FEL). The wide and …

In the last decade, we have experienced massive progress in spectroscopic methods for
mass-selected ions. The aim of this tutorial review is to present action spectroscopy as a …

A corner stone in the study of the size‐dependent properties of cluster ions in the gas phase
is their structural characterization. Over the last 10 years, significant progress has been in …

Studying metal ion solvation, especially hydration, in the gas phase has developed into a
field that is dominated by a tight interaction between experiment and theory. Since the …

The harmonic approximation provides a powerful approach for interpreting vibrational
spectra. In this treatment, the energy and intensity of the 3N− 6 normal modes are calculated …

Infrared photodissociation spectroscopy is reported for mass-selected Ni+ (H2O) n
complexes in the O− H stretching region up to cluster sizes of n= 25. These clusters fragment …

We investigate activation of carbon dioxide by singly charged hydrated magnesium cations
Mg.+(H2O) n, through infrared multiple photon dissociation (IRMPD) spectroscopy combined …

Beginning in the mid-1980s, a number of innovative experimental studies on ionic clusters
emerged from the laboratory of Yuan T. Lee combining infrared laser spectroscopy and …

Studies of gas phase M+ (L) n cluster ions (where M is a metal atom and L is a ligand
molecule) assist our understanding of solvation and chemical processes that involve metal …

Infrared photodissociation spectra of buffer-gas-cooled [MgNO3 (H2O) n]+ complexes with
n= 1− 4 are measured in the O− H stretching region. The observed bands are assigned to …
