Zeitaufgelöste Fluoreszenzspektroskopie unimolekularer Reaktionen im Überschalldüsenstrahl: <i>trans-cis</i>-Photoisomerisierung, Phenylringtorsion, intramolekularer Wasserstoffatomtransfer
(2005-11-02)In this work three types of unimolecular reactions were studied spectroscopically and theoretically with model systems: (1) the trans-cis-photoisomerization of trans-stilbene and its ... -
Zeitaufgelöste inelastische Neutronenstreuung an entmischenden Silber-Natriumchlorid-Einkristallen
(2002-11-20)The kinetic of decomposition in silver sodium chloride single crystals has been studied by means of the evolution of phonon spectra. In the early stages of decomposition a spinodal ... -
