  1. 1. Photochemistry of Phenyl Halides

    Författare :Daniel Karlsson; Jan Davidsson; Michael Ashfold; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Photochemistry; Predissociation; Phenyl halides; Excited states; Substituent effects; Pump-probe spectroscopy; Molecular beam; Dynamics; Kemi; Chemistry; Kemi;

    Sammanfattning : We have studied fundamental aspects of photo-induced dissociation kinetics and dynamics in several phenyl halides. By combining femtosecond pump-probe measurements with ab initio calculations we are able to account for several observations. LÄS MER

  3. 2. Experimental and theoretical studies of some transition metal halides

    Författare :Raimo Koivisto; John Brown; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Sammanfattning : This thesis comprises both experimental and theoretical studies on transition metal (TM) containing molecules and then mainly on CrF and CrCl. Both the experimental and theoretical parts have been aimed at a depend understanding of the electronic structure. LÄS MER

  7. 5. Ultrafast Photo-induced Reaction Dynamics of Small Molecules

    Författare :Malin Kadi; Jan Davidsson; Eva Åkesson; Sören Keiding; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; pump-probe spectroscopy; reaction dynamics; photodissociation; aryl halides; spin-orbit coupling; ab initio calculations; molecular dynamics; vibrational wavepackets; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : The main focus of this thesis is the investigation of the dissociation dynamics of aryl halides using femtosecond pump-probe spectroscopy. In the monohalogenated aryl halides, iodo-, bromo- and chlorobenzene, the rate of dissociation following excitation at 266 nm in the gas phase increased with increasing mass of the halogen atom.
