The low density of ions in mass spectrometers generally precludes direct infrared (IR)
absorption measurements. The IR spectrum of an ion can nonetheless be obtained by …

This review provides a comprehensive overview of the applications of helium nanodroplets
in the study of ensembles of atoms and molecules, ie clusters and complexes. These …

A comprehensive study of the OH and OD stretching fundamentals in clusters of methanol
and its isotopomers CH 3 OD⁠, CD 3 OH⁠, and CD 3 OD provides detailed insights into the …

We have calculated frequencies and intensities of fundamental and overtone vibrational
transitions in water and water dimer with use of different vibrational methods. We have …

The vibrational spectroscopy of the water dimer provides an understanding of basic
hydrogen bonding in water clusters, and with about one water dimer for every 1,000 water …

Water dimers have been assembled in He droplets and studied by infrared laser depletion
spectroscopy. All four OH stretching bands of the dimer have been identified in the spectral …

We consider how the infrared intensity of a hydrogen-bonded OH stretch varies from weak to
strong H-bonds using a theoretical model. We obtain trends for the fundamental and …

For more than two decades, encapsulation in superfluid helium nanodroplets has served as
a reliable technique for probing the structure and dynamics of molecules and clusters at a …

A series of (H2O) n clusters ranging from the dimer to the hexamer have been characterized
with the CCSD (T) and the 2-body: Many-body CCSD (T): MP2 methods near the complete …

A hydrogen bond network in ammonia clusters plays a key role in understanding the
properties of species embedded in ammonia. This network is dictated by the structures of …
