  4. 13. Making Radical Cations Live Longer

    Författare :Ola Persson; Kemisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; spin trapping.; 3-hexafluoropropan-2-ol; 3; 1; thallium III -based oxidants; Radical cations; electron paramagnetic resonance; Physics; Fysik; Chemistry; Kemi;

    Sammanfattning : The acid-catalyzed rearrangement of 1,4,5,8-tetramethylnaphthalene was used to determine the acidity of media used for EPR spectral studies of radical cations. The radical cations of methyl-substituted naphthalenes were shown to undergo dimerization reactions. LÄS MER

  5. 14. Laboratory and Stellar Spectra in High Resolution: Studies of Fe, Pt and Tl in Peculiar Stars

    Författare :Gabriele Kalus; Fysiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; high-resolution spectroscopy; hyperfine structure; peculiar stars; iron; platinum; lead; upsilon Sagittarii; HR7775; chi Lupi; isotope shift; Atomic and molecular physics; Atom- och molekylärfysik; Fysicumarkivet A:1997:Kalus;

    Sammanfattning : The near-infrared spectrum of upsilon Sagittarii has been registered using the SOFIN high resolution spectrometer on the Nordic Optic Telescope, La Palma. For the first time 4f-5g transitions of Fe II in any astrophysical spectrum have been identified. LÄS MER

  7. 15. Temperature Dependent in situ Studies of two Simple Structure Types Revealing Modulation : or the Art of Making Glitter

    Författare :Laura Folkers; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Crystallography; Modulation; Intermetallics;

    Sammanfattning : In the first part of this thesis, three intermetallic compounds are discussed, that were originally thought of as thallium iodide type compounds. Starting from small evidence that there is more than meets the eye, investigations began to find the true structure of AuIn. LÄS MER
