  3. 17. Chemical reactivities as a mirror of environmental transformations - method development and assessment of some selected organohalogens

    Författare :Lisa Granelli; Åke Bergman; Johan Eriksson; Roland Kallenborn; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Miljökemi; miljökemi; Environmental Chemistry;

    Sammanfattning : The assement of chemical persistence is an important part of legislative protection of the environment and human health. Of the vast number of chemicals on the market today few have been properly assessed. LÄS MER

  4. 18. Investigations of some diatomic molecules : the hydrides of selenium, antimony and silicon and the platinum oxide

    Författare :Ulf Sassenberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis is an extension and a summary of investigations on the electronic spectra of gaseous SeH/D, SbH/D, PtO and to some minor extent also of gaseous SiH. Rotational analyses are performed on each molecule.SeH/D molecules were generated in photolysis reactions using 12 µs long light flashes. LÄS MER

  5. 19. A Study of the Interaction between the HOO radical and some small Molecules

    Författare :Thomas Svensson; Kemisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Physical chemistry; ab initio; peroxy radical; molecular interactions; matrix isolation; FTIR; infrared; Chemistry; Kemi;

    Sammanfattning : The HOO radical is a key intermediate in the atmosphere and is involved in a large number of reactions, including ozone loss cycles in the stratosphere and oxidation processes in the troposphere. This theses is a study of the HOO radical and its interactions with a number of small molecules that are present in the atmosphere. LÄS MER

  7. 20. Towards optical diagnostics and control in aerotaxy semiconductor nanowire growth

    Författare :Per Samuelsson; Förbränningsfysik; []
