  2. 1. X-ray spectroscopy on diatomic and cationic molecules

    Author : Ludvig Kjellsson; Jan-Erik Rubensson; Marcus Agåker; Monica Turcato; Michael Meyer; John Bozek; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; X-ray absorption spectroscopy; resonant inelastic X-ray scattering; cationic molecule; dinitrogen; dioxygen; carbon monoxide; aqueous hydroxyl radical; lifetime-vibrational interference; RIXS; XAS; LVI; N2; O2; CO; H2O; OH;

    Abstract : X-ray spectroscopy have been used to study the electronic structure of diatomic and cationic molecules. X-ray absorption spectra of the molecular cations N2+, O2+, and CO+ have been measured. READ MORE

  4. 2. Applications of Short Extreme Ultraviolet Pulses to the Spectroscopy of Atoms and Molecules

    Author : Allan Johansson; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; High-order harmonics; short pulses; pulse characterisation; sidebands; lifetime measurements; time domain spectroscopy; frequency domain spectroscopy; He; N2; CO; XUV; Atomic and molecular physics; relative polarisation; Atom- och molekylärfysik; Fysicumarkivet A:2003:Johansson;

    Abstract : This thesis is devoted to the characterisation in time and frequency, and to spectroscopic application, of extreme ultraviolet (XUV) pulses. High-order harmonic generation or wave mixing processes were used to produce the pulses in the XUV spectral region. READ MORE

  5. 3. Reactivity of Metal Clusters with Diatomic Molecules

    Author : Lotta Holmgren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nbn; cluster; reactivity; Rhn; NO; D2; CO; N2; laser vaporization; Wn; Nin; photoionization; time-of-flight mass spectrometer; ionization potential; Cun; O2; Vn;

    Abstract : The reactivity of transition-metal clusters, in the approximate size range 10-60 atoms, with diatomic molecules has been investigated. A pulsed beam of neutral clusters is produced by a laser-vaporization source and passed through a low-pressure reaction cell containing the reactive gas. READ MORE

  6. 4. Metal Cluster Reactivity. Adsorption of small molecules in biomolecular collisions

    Author : Mats Andersson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; O2; CO; ionization potential; Con; Fen; NO; sticking probability; laser ionization; D2; Wn; Cun; Rhn; reaction probability; cluster; jellium model; Nbn; metal cluster reactivity; N2; time-of-flight mass spectrometry; Nin;

    Abstract : Metal clusters can be characterized as the tiniest possible metal particles, containing only an easily counted number of atoms. In this work, reactions between metal clusters and diatomic molecules have been investigated. We have constructed an experimental set-up to produce and detect clusters, and to investigate their chemical reactivity. READ MORE

  7. 5. Development of Dual-broadband Rotational CARS for Combustion Diagnostics

    Author : Joakim Bood; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; N2; O2; C2H2; Dimethyl Ether DME ; High pressure; Stray light filtering; multi-point CARS; CARS; Temperature; Engine knock; Physics; Fysik; Fysicumarkivet A:2000:Bood;

    Abstract : The present thesis concerns development and application of dual-broadband rotational coherent anti-Stokes Raman spectroscopy (DB-RCARS) for temperature and species concentration measurements in combustion processes. Both fundamental development of the technique, including experimental as well as modelling results, and measurements in practical combustion devices were conducted. READ MORE
