A cluster is an aggregate of bound atoms or molecules, intermediate in size between a
molecule and a bulk solid. Clusters of a variety of molecules are receiving increasing …

The ability of Paul and Penning traps to contain ions for time periods ranging from
milliseconds to minutes allows the trapped ions to be subjected to laser irradiation for …

In this article, the new and exciting techniques of infrared consequence spectroscopy
(sometimes called action spectroscopy) of gaseous ions are reviewed. These techniques …

The precise relationship between native gas-phase protein ion structure, charge,
desolvation, and activation remains elusive. Much evidence supports the Charge Residue …

The atomic-scale fragmentation processes involved in molecules undergoing hypervelocity
impacts (HVIs; defined as> 3 km/s) are challenging to investigate via experiments and still …

We report the first IR spectroscopic observation of carboxylate stretching modes in free
space, ie, in the complete absence of solvent or counterions. Gas-phase spectra of a series …

Structural properties of over 55 small proteins have been determined using both density-
based and wave-function-based electronic structure methods in order to assess the ability of …

Isolation of biomolecules in vacuum facilitates characterization of the intramolecular
interactions that determine three-dimensional structure, but experimental quantification of …

Three different commonly used infrared photodissociation (IRPD) spectroscopy acquisition
and analysis methods are described, and results from these methods are compared using …

Understanding the mechanisms and energetics of ion solvation is critical in many scientific
areas. Here, we present a methodlogy for studying ion solvation using differential mobility …
