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 …

Infrared multiple photon dissociation (IRMPD) spectroscopy allows for the derivation of the
vibrational fingerprint of molecular ions under tandem mass spectrometry (MS/MS) …

Gas-phase infrared multiple photon dissociation (IRMPD) spectra have been recorded for
the conjugate bases of a series of amino acids (Asp, Cys, Glu, Phe, Ser, Trp, Tyr). The …

Theoretical spectroscopy is mandatory for a precise understanding and assignment of
experimental spectra recorded at finite temperature. We review here room temperature DFT …

The development of new ion activation techniques continues to be a dynamic area of
scientific discovery, in part to complement the tremendous innovations in ionization methods …

We describe here a study of the spectroscopy of two peptides that we expect to be helical,
Ac-Phe-(Ala) 5-Lys-H+ and Ac-Phe-(Ala) 10-Lys-H+, and one that we expect to be globular …

The identification of molecular biomarkers is critical for diagnosing and treating patients and
for establishing a fundamental understanding of the pathophysiology and underlying …

The well-known correlation between structure and functionality has motivated generations of
scientists to intensively investigate the structural behaviour of peptide and protein systems …

To improve our understanding of uranium toxicity, the determinants of uranyl affinity in
proteins must be better characterized. In this work, we analyzed the contribution of a …
