Ion mobility measurements can be used to obtain structural information for large polyatomic
ions in the gas phase. The methods are flexible and can be applied to a wide range of …

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 …

Quantum states may exhibit asymmetry with respect to the action of a given group. Such an
asymmetry of states can be considered a resource in applications such as quantum …

The maximum charge zmax on a variety of electrospray ions of globular proteins retaining
their native structure, as well as naturally compact starburst dendrimers is compared to the …

Although nonnative protein conformations, including intermediates along the folding
pathway and kinetically trapped misfolded species that disfavor the native state, are rarely …

Ion mobility measurements have been used to examine the geometries of naked BPTI
(bovine pancreatic trypsin inhibitor) and cytochrome c ions in the gas phase, as a function of …

Electrospray ionization mass spectrometry (ESI-MS) has demonstrated utility for the
detection and study of weakly bound, noncovalent complexes, including protein interactions …

An ion mobility/mass spectrometry technique has been developed to record mass-resolved
ion mobility distributions for multiple ions simultaneously. The approach involves a new …

The origin of asymmetric charge and mass partitioning observed for gas-phase dissociation
of multiply charged macromolecular complexes has been hotly debated. These experiments …

This article provides a review of recent studies of the properties of unsolvated (and partially
solvated) peptides and proteins. The methods used to produce vapor-phase peptide and …
