1 Morse, Michael DavidResonant two-photon ionization spectroscopy of jet-cooled PdSiThe spectra of diatomic PdSi have been investigated for the first time, using the technique of resonant two-photon ionization spectroscopy. A number of vibronic transitions have been observed in the 20 400?22 000 cm?1 range. It is difficult to group the bands into band systems, although one likely...2011
2 Morse, Michael DavidResonant two-photon ionization spectroscopy of jet-cooled OsN: 520?418 nmThe optical transitions of supersonically cooled OsN have been investigated in the range from 19 200 to 23 900 cm?1 using resonant two-photon ionization spectroscopy. More than 20 vibronic bands were observed, 17 of which were rotationally resolved and analyzed. The ground state is confirmed to be 2...2011
3 Morse, Michael DavidElectronic structure of the 4 d transition metal carbides: dispersed fluorsecence spectroscopy of MoC, RuC, and PdCDispersed fluorescence studies of the diatomic molecules MoC, RuC, and PdC are reported. New states identified in MoC and RuC are the [...]2??12??, ?,??? states and the [...]2??12??, ??? state, respectively. Five states are observed by dispersed fluorescence in PdC. The ground state is found to be [...2011
4 Armentrout, Peter B.Guided ion beam and theoretical study of the reactions of Au+ with H2, D2, and HDReactions of the late third-row transition metal cation Au+ with H2, D2, and HD are examined using guided ion beam tandem mass spectrometry. A flow tube ion source produces Au+ in its 1S (5d10) electronic ground state level. Corresponding state-specific reaction cross sections for forming AuH+ an...2011
5 Morse, Michael DavidSpectroscopy of diatomic ZrF and ZrCl: 760 ? 555 nmThe optical spectrum of diatomic ZrF has been investigated, with transitions recorded in the range from 14 700 to 18 000 cm?1. Many bands have been observed, several of which can be grouped into three band systems. Rotationally resolved investigations are hampered by perturbations that are rampant ...2011
6 Morse, Michael DavidDetection of nonpolar lons in 2?3/2 States by Radioastronomy via Magnetic Dipole TransitionsThe possibility of magnetic dipole-induced pure rotational transitions in the interstellar medium is investigated for symmetric Hund?s case (a) linear molecules, such as H-C?C-H+(X~2?3/2u), CO2+ (X~2?3/2g), H-C?C-?C-H+ (X~2?3/2g), and N3 (X~2?3/2g). These species lackan electric dipole moment and th...2011
7 Armentrout, Peter B.Guided ion beam and theoretical study of the reactions of Os + with H 2, D 2, and HDReactions of the third-row transition metal cation Os+ with H2, D2, and HD to form OsH+ (OsD+) were studied using a guided ion beam tandem mass spectrometer. A flow tube ion source produces Os+ in its 6D (6s15d6) electronic ground state level. Corresponding state-specific reaction cross sections are...2011
8 Armentrout, Peter B.Communication: Theoretical exploration of Au++ H2, D2, and HD reactive collisionsA quasi-classical study of the endoergic Au+(¹S) + H₂(X¹Σ+g) → AuH+ (²Σ+) + H(²S) reaction, and isotopic variants, is performed to compare with recent experimental results [F. Li, C. S. Hinton, M. Citir, F. Liu, and P. B. Armentrout, J. Chem. Phys. 134, 024310 (2011)]. For this purpose, a ...2011
9 Armentrout, Peter B.Sequential bond energies and barrier heights for the water loss and charge separation dissociation pathways of Cd2+(H2O)n, n 3-11The bond dissociation energies for losing one water from Cd2+(H2O)n complexes, n=3?11, are measured using threshold collision-induced dissociation in a guided ion beam tandem mass spectrometer coupled with a thermal electrospray ionization source. Kinetic energy dependent cross sections are obtained...2011
