Hydrogen bonds1, 2 are one of the principal intermolecular forces. A special class are ionic
hydrogen bonds (IHBs) that form between ions and molecules with bonds strengths of 5-35 …

Over the past 15 years the high-resolution spectroscopic study of ionic complexes has
grown into an active field with relevance to significant physical, chemical, and biological …

1.1. Historical Background Hydrogen bonds 1, 2 are one of the principal intermolecular
forces. A special class are strong ionic hydrogen bonds (IHBs) that form between ions and …

A new approach for studying the photoisomerization of molecular ions in the gas phase is
described. Packets of molecular ions are injected into a drift tube filled with helium buffer …

As part of an extended fundamental study on the interaction of molecular hydrogen with the
surfaces of potential storage materials, this work describes the interaction of dihydrogen with …

Infrared photodissociation spectra of SiOH+–X dimers with X= He, Ne, Ar, and N2 are
analyzed in the vicinity of the O–H stretch (ν1) vibration of SiOH+. The observed …

We describe recent infrared spectroscopic investigations of charged complexes consisting of
a hydrogen or deuterium molecule attached to an atomic metal cation, including complexes …

Mid-infrared vibrational spectra of He–HN2 and He2–HN2 have been recorded by
monitoring their photofragmentation in a tandem mass spectrometer. For He–HN2 three …

The 1 band of Ne–HCO has been recorded for both 20Ne and 22Ne containing isotopomers
by means of infrared photodissociation spectroscopy. The rotational structure of the band is …

Infrared photodissociation spectra of mass-selected SiOH+–Arn complexes (n= 1–10) have
been recorded in the vicinity of the OH stretch (ν1) vibration of SiOH+. The SiOH+–Ar dimer …
