The Onset for Vibrationally Induced, Intramolecular Proton Transfer at Three Water Molecules in Microhydrated 4-Aminobenzoic Acid Open
Protonation of 4-aminobenzoic acid occurs at either the amino group (the N-protomer, N) or at the carboxylic acid C═O group (the O-protomer or O). N lies higher in energy than O in the isolated ion but becomes the more stable of the 4ABAH+…

The pKa's of acids are known to depend on the ionic strength of an electrolyte solution, an effect that qualitatively results from electrostatic interactions of the acid and conjugate base with proximal ions. Here, we explore an intramolec…

Demonstration of Capture, Cooling, Tagging, and Spectroscopic Characterization of UV Photoproduct Ions in a Cryogenic Ion Trap: Application to 266 nm Photofragment Ions from Rhodamine 6G Open
We demonstrate a method to determine the structures of the primary photodissociation products from a cryogenically cooled parent ion. In this approach, a target ion is cooled by a pulse of buffer gas and tagged in a 20 K Paul trap. The col…

HIGH RESOLUTION SPECTROSCOPY IN A 5K CRYOGENIC ION TRAP: REVISITING THE OH STRETCHING BANDS OF THE Hâ‚‚O AND HDO ISOTOPOLOGUES OF THE BINARY COMPLEXES WITH IODIDE Open
We report fully rotationally resolved spectra of the I -(H 2 O) and I -(HDO) ion-molecule complexes measured by predissociation spectroscopy in a 3D cryogenic ion trap.The spectra were obtained by excitation with a single-frequency, cw inf…

High-resolution vibrational predissociation spectroscopy of I <sup>−</sup> · H <sub>2</sub> O by single-mode CW infrared excitation in a 3D cryogenic ion trap Open
We describe the integration of a tunable, single-mode, continuous wave infrared laser into a cryogenic ion spectroscopy experiment to measure the rovibrational spectrum of the I-∙H2O complex in the OH stretching region. These upper levels …
