Experimentelle und theoretische Untersuchungen der Dissoziationen von Tetrafluorethen, Hexafluorpropen und Hexafluorcyclopropan
(2014-07-17)The thermal dissociation reactions of C2F4, C3F6 and c-C3F6 were studied in shock waves monitoring CF2 radicals by their UV absorption.
C2F4: The absorption coefficients as functions of wavelength and temperature ... -
Stoßwellenuntersuchungen und Modellierung der Pyrolyse von Pentafluorethan und 2-H-Heptafluorpropan
(2014-02-20)The pyrolysis of C2HF5 and C3HF7 have been studied in shock waves by monitoring die UV-absorption of CF2 at 248nm and temperatures in the range of 1400 - 2000 K. Ar was used as bath gas with concentrations in the range ... -
Laserspektroskopische Untersuchungen zur Dynamik von ionischen Flüssigkeiten mit Hilfe molekularer Sonden
(2011-08-24)Ionic liquids have been studied by transient absorption spectroscopy. Relaxation processes after photo excitation of molecular probes were used as an indicator to study the microscopic ... -
Femtosekunden Photodetachment- Photoelektronenspektroskopie an isolierten und massenselektierten Halogen-Edelgas-Clustern
(2010-11-22)This thesis is dedicated to the study of the energetics and dynamics of the solvation process in van-der-Waals bonded halogen rare gas clusters. To this end a high repetitive electron-/mass ... -
Pressure and temperature dependence of recombination reactions of benzyl-type radicals
(2009-02-18)The combination reactions p-F-C6H4CH2 + p-F-C6H4CH2 (+M) → C14H12F2 +M), p-CH3-C6H4CH2 + p-CH3-C6H4CH2 (+M) → C16H18 (+M) and C6H5CH2 + C6H5CH2 (+M) → C14H14 (+M) have been investigated ... -
Dynamics, Ionization and Charge Separation in Superheated Metastable Water
(2008-10-02)Heating up a water filament in vacuum with an infrared(IR)-laser generates superheated metastable water, which undergoes an ultrafast phase expansion. Molecular Dynamics (MD) ... -
Untersuchung der synaptischen Neurotransmitterfreisetzung mit kombiniert elektrophysiologischen und bildgebenden Verfahren
(2006-04-25)Neuronal networks in the brain are comprised of a mixture of excitatory and inhibitory neurons. The excitatory and inhibitory cells play distinct roles in the functional network since the ... -
Der Einfluß von chemischer Konstitution, Symmetrie und molekularer Umgebung auf die intramolekulare Schwingungsrelaxation aromatischer Moleküle
(2006-03-24)This thesis focuses on elucidating mechanisms of intramolecular vibrational energy redistribution (IVR). It constitutes a comparative study on structurally closely related aromatic molecules ... -
Photolytischer Käfigeffekt von Dihalomethanen in überkritischen Lösungsmitteln
(2005-12-05)This thesis deals with the effects that a dense environment may have on chemical reactions. For this purpose a seemingly simple reaction was chosen: the photodissociation of diiodomethane ... -
Dynamics of the B-A Transition of DNA Double Helices
(2005-05-20)Although the B-A transition of DNA is known for about 50 years, the dynamics of this transition has not been characterized yet. Experiments with stopped flow instrument showed that the ... -
ps-UV-Pump REMPI-Probe Spektroskopie an <i>trans</i>-Stilben van-der-Waals-Clustern im Überschalldüsenstrahl
(2001-07-18)The reaction rate of the unimolecular trans-cis-isomerization of trans-stilbene in the first excited state (S1) is influenced by cluster formation. Photoinduced reactions of ...
