    Nonlinear absorption spectroscopy of the ethane molecule (1977)
    Springer
    Applied physics 14 (1977), S. 343-350

    Notizen: Abstract By means of nonlinear absorption spectroscopy data necessary for the interpretation of molecular spectra can be obtained in such spectral regions, where conventional spectroscopic methods yield only a quasi-continuous absorption curve. Using a Zeeman-tuned He−Ne laser at the wavelength of 3.39μm we have measured significant differences in the intensity and temperature behaviour for several ethane absorption lines, the analysis of which made possible a preliminary qualitative assignment of these lines.

    Laser photolytic deposition of molybdenum and tungsten thin film microstructures (1990)
    Springer
    Applied physics 50 (1990), S. 233-235

    Notizen: Abstract We have deposited thin metal films of Mo and W with sub-μm lateral resolution using the photodissociation of the carbonyls by the frequency doubled radiation of an Arion laser at cw and ps-pulse operation, respectively. In both regimes similar curves are obtained for the intensity dependence of the deposition rate. No difference was observed for the lateral resolution using cw or ps-pulse irradiation. Measurements of the deposition rate as a function of the spot size indicate that the decomposition occurs in the adsorbed phase.

    Spectral characteristics of IR-multiphoton excitation in supersonic molecular beams (1985)
    Springer
    Applied physics 38 (1985), S. 179-184 
    Details
    ISSN: 1432-0649

    Thema: Physik
    Notizen: Abstract The multiphoton absorption of SF6 was investigated in supersonic molecular beams in dependence on the fluence and the wavelength of the CO2 laser. The temperatures of the SF6 molecules have been reduced using seeded beams of different concentrations. The experimental results are discussed on the basis of the known spectroscopic data of SF6 and provide some novel information about the spectral characteristics of the ir-multiphoton excitation of strongly cooled molecules in the collision-free case.

    Excimer laser photolysis of molybdenum hexacarbonyl with buffer gas (1989)
    Springer
    Applied physics 49 (1989), S. 301-305 
    Details
    ISSN: 1432-0649
    Schlagwort(e): 82.50 ; 81.15
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Physik
    Notizen: Abstract We have studied the photolysis of molybdenum hexacarbonyl by focused excimer laser radiation. It was found that electronically excited Mo atoms detected in the focus region of a KrF laser are due to a direct two photon absorption transition. The upper limit of the energy for complete dissociation of Mo(CO)6 has been derived from these results. Two photon dissociation in the gas phase should be the dominant process at metal film deposition on substrates positioned perpendicularly and near to the focus. Adding buffer gases to the organometallic vapor particle formation was observed in the whole irradiated gas volume. The analysis of scattered He-Ne laser light yields information about the density and size of these particles. Some conclusions are drawn with respect to structured metal film deposition with high spatial selectivity.

    Resonant two-photon ionization spectroscopy of C6H6-(SF6)1,2 (1993)
    Springer
    The European physical journal 26 (1993), S. 213-216

    ISSN: 1434-6079

    Thema: Physik
    Notizen: Abstract Vibrationally resolved electronic spectra of heteroclusters C6H6-SF6 and C6H6-(SF6)2 were studied in the spectral regions near the S0-S1, 0 0 0 and 6 0 1 transitions of the benzene monomer. A nonvanishing 0 0 0 vibrational band has been observed for C6H6-SF6 with a C3v symmetry. For both clusters we have determined the ionization potentials as well as the binding energies in the electronic ground state and the ionization state. The fragmentation of larger clusters (C6H6)n(SF6)m is restricted to the loss of SF6 molecules while the emission of C6H6 molecules have not been observed.
