TL;DR: How cryogenic cooling, mass selection, and reactive processing together provide a powerful way to characterize ion structures as well as rationally synthesize labile reaction intermediates is discussed.

TL;DR: The onset of extensive water-water hydrogen bonding is observed starting with four water molecules and persists in the larger clusters, indicating an ion with a highly symmetric solvation shell.

TL;DR: General trends in the stepwise solvation motifs of the bicarbonate anion can be deduced from the overall agreement between the calculated and experimental spectra.

TL;DR: Analysis of the resulting band patterns indicates that only one isomeric form is generated upon cooling the ions initially at room temperature into the H(2) tagging regime, indicating that each C=O oscillator contributes a single distinct band, effectively "reporting" its local chemical environment.

TL;DR: A versatile and sensitive spectroscopic probe of functional groups engaged in hydrogen bonding in such contexts is presented, measurement of the frequency changes in specific covalent bonds upon complex formation, information drawn from otherwise transient complexes that have been extracted from solution and conformationally frozen near 10 kelvin in gas-phase clusters.
