    Abstract : In this licentiate thesis the luminescence properties of two flexible conjugated dyes have been studied. The first, Pt1, is a platinum(II) acetylide chromophore used in optical power limiting materials. READ MORE

  5. 3. Atomic decomposition of molecular properties

    Author : Ignat Harczuk; Hans Ågren; Olav Vahtras; Per-Olof Åstrand; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

    Abstract : In this thesis, new methodology of computing properties aimed for multipleapplications is developed. We use quantum mechanics to compute propertiesof molecules, and having these properties as a basis, we set up equations basedon a classical reasoning. READ MORE

  6. 4. Dynamics of multiphoton processes in nonlinear optics and x-ray spectroscopy

  7. 5. Methods of laser spectroscopy in the study of Pb₂, CaCl and CaH

    Author : Hans Martin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Some methods of laser spectroscopy in the study of small molecules are discussed. A special emphasis is given on to how quantum number assignments can be made and rotational analyses of very dense structures can be carried out after exciting the molecules with monochromatic radiation.
