Isolated transition metal clusters have been established as useful models for extended metal
surfaces or deposited metal particles, to improve the understanding of their surface …

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 …

In this review, we present an overview of our recent work on the infrared spectroscopy of
mass-selected gas-phase molecular ions. The ions are stored and isolated in a quadrupole …

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 …

Recently developed analytic third-derivative methods for self-consistent-field (SCF)
wavefunctions have made it possible to theoretically determine a number of anharmonic …

The gas phase infrared spectra of the hydrated hydronium cluster ions H3O+⋅(H2O) n (n= 1,
2, 3) have been observed from 3550 to 3800 cm− 1. The new spectroscopic method …

Remington and Schaefer. Observation of the hydrogen-bonded OH stretch in 30+·(20) 3 at
2670 cm" 1 confirmed the assignment of the low-resolution spectrum obtained by Schwarz …

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 …

Recent advances in the gas phase vibrational spectroscopy of mass-selected ions are
described, highlighting experiments on hydrogen-bonded (HBed) clusters relevant to …

Infrared spectra of hydrated hydronium ions weakly bound to an H2 molecule, specifically
H7O+ 3⋅ H2 and H9O+ 4⋅ H2, have been observed. Mass‐selected parent ions, trapped in …
