Infrared multiple photon dissociation spectroscopy of group I and group II metal complexes with Boc-hydroxylamine
Dain, Ryan P.; Gresham, Garold L.; Groenewold, Gary S.; Steill, Jeffrey D.; Oomens, Jos; Van Stipdonk, Michael J. (WILEY-BLACKWELL, 2013-08-30)RATIONALE Hydroxamates are essential growth factors for some microbes, acting primarily as siderophores that solubilize iron for transport into a cell. Here we determined the intrinsic structure of 1:1 complexes between ... -
Infrared multiple photon dissociation spectroscopy of sodium and potassium chlorate anions
Dain, Ryan P.; Leavitt, Christopher M.; Oomens, Jos; Steill, Jeffrey D.; Groenewold, Gary S.; Van Stipdonk, Michael J. (John Wiley and Sons, 2010-01-01)The structures of gas-phase, metal chlorate anions with the formula [M(ClO(3))(2)](-), M = Na and K, were determined using tandem mass spectrometry and infrared multiple photon dissociation (IRMPD) spectroscopy. Structural ... -
Infrared multiple-photon dissociation spectroscopy of group II metal complexes with salicylate
Dain, Ryan P.; Gresham, Garold L.; Groenewold, Gary S.; Steill, Jeffrey D.; Oomens, Jos; Van Stipdonk, Michael J. (John Wiley and Sons, 2011-07-15)Ion trap tandem mass spectrometry with collision-induced dissociation, and the combination of infrared multiple-photon dissociation (IRMPD) spectroscopy and density functional theory (DFT) calculations, were used to ... -
IRMPD and DFT study of the loss of water from protonated 2-hydroxynicotinic acid
Van Stipdonk, Michael J.; Kullman, Michael J.; Berden, Giel; Oomens, Jos (Elsevier, 2012-07-06)Collision-induced dissociation (CID) of protonated 2-hydroxynicotinic acid (2-OHNic) generates a dominant product ion through loss of 18 mass units, presumably the elimination of water. Subsequent isolation and storage of ... -
IRMPD spectroscopy b2 ions from protonated tripeptides with 4-aminomethyl benzoic acid residues
Kullman, Michael J.; Molesworth, Samuel P.; Berden, Giel; Oomens, Jos; Van Stipdonk, Michael J. (Elsevier, 2012-02)Collision-induced dissociation (CID) of the peptide alanine-4-aminomethylbenzoic acid-glycine, A(AMBz)G generates a prominent b2 ion despite a previous report [E.R. Talaty, T.J. Cooper, S.M. Osburn, M.J. Van Stipdonk, ... -
IRMPD spectroscopy of anionic group II metal nitrate cluster ions
Leavitt, Christopher M.; Oomens, Jos; Dain, Ryan P.; Steill, Jeffrey D.; Groenewold, Gary S.; Van Stipdonk, Michael J. (Springer, 2009-05-01)Anionic group II metal nitrate clusters of the formula [M(2)(NO(3))(5)](-), where M(2) = Mg(2), MgCa, Ca(2), and Sr(2), are investigated by infrared multiple photon dissociation (IRMPD) spectroscopy to obtain vibrational ... -
Spectroscopic evidence for mobilization of amide position protons during CID of model peptide ions
Molesworth, Samuel P.; Leavitt, Christopher M.; Groenewold, Gary S.; Oomens, Jos; Steill, Jeffrey D.; Van Stipdonk, Michael J. (Springer, 2009-10-01)Infrared multiple photon dissociation (IRMPD) spectroscopy was used to study formation of b2+ from nicotinyl-glycine-glycine-methyl ester (NicGGOMe). IRMPD shows that NicGGOMe is protonated at the pyridine ring of the ... -
Spectroscopic investigation of H atom transfer in a gas-phase dissociation reaction: McLafferty rearrangement of model gas-phase peptide ions
Van Stipdonk, Michael J.; Kerstetter, Dale R.; Leavitt, Christopher M.; Groenewold, Gary S.; Steill, Jeffrey D.; Oomens, Jos (Royal Society of Chemistry, 2008-06-14)Wavelength-selective infrared multiple-photon photodissociation (WS-IRMPD) was used to study isotopically-labeled ions generated by McLafferty rearrangement of nicotinyl-glycine-tert-butyl ester and betaine-glycine-tert-butyl ...
