IR spectroscopy reveals the competition between two nonconventional hydrogen bonds involving Si: SiH⋯HO dihydrogen bond (DHB) versus SiH⋯Si charge inverted hydrogen bond (CIHB).
Mode- and size-specific dissociation dynamics of vibrationally excited H3O+–Ar and H+(H2O)2–Ar is investigated using a photofragment ion-imaging system designed for mass-selected ions.
We explore the effects of microhydration on the aromatic charge resonance (CR) interaction of the prototypical pyrrole dimer cation (Py2+) by infrared spectroscopy and quantum chemical calculations.
The OH stretching overtone region of micro-solvated hydronium ions was explored by NIR spectroscopy and anharmonic vibrational simulations.
Puzzling isomer competition, revealed through infrared spectroscopy of protonated ethanol tetramers with varied tagging, is investigated using energy landscapes of neural network potentials developed with density functional theory accuracy.
