Rotational action spectroscopy is an experimental method in which rotational spectra of
molecules, typically in the microwave to sub-mm-wave domain of the electromagnetic …

The procedure leading to the first HyDRA blind challenge for the prediction of water donor
stretching vibrations in monohydrates of organic molecules is described. A training set of 10 …

Advanced vibrational spectroscopic experiments have reached a level of sophistication that
can only be matched by numerical simulations in order to provide an unequivocal analysis …

Aminobenzoic acid (4ABA) is a biologically relevant, small organic molecule with two
protonation sites: the amino group (N-protomer) and the carboxyl group (O-protomer). The O …

A linear cryogenic 16-pole wire ion trap has been developed and constructed for cryogenic
ion spectroscopy at temperatures below 4 K. The trap is temperature-variable, can be …

The geometry of biomolecules isolated in the gas phase usually differs substantially from
their native structures in aqueous solution, which are the only ones truly relevant to life …

The native-like structures of protonated glycine and peptide Gly3H+ were elucidated using
cold ion IR spectroscopy of these biomolecules hydrated by a controlled number of water …

Multipole radiofrequency ion traps are versatile tools for trapping and manipulating ions. The
extraction of ions from such a trap leads to broad time-of-flight (ToF) distributions, which …

The photodynamics of protonated tryptophan and its mono hydrated complex TrpH+− H2O
has been revisited. A combination of steady‐state IR and UV cryogenic ion spectroscopies …

Chiral recognition between tryptophan (Trp) and carbohydrates such as d-glucose (d-Glc),
methyl-α-d-glucoside (d-glucoside), d-maltose, and d-cellobiose in cold gas-phase cluster …
