Isomerization of CO on a NaCl(100) Surface: Evidence for Resonance Enhanced Quantum Tunneling in Condensed Phase
(2024-06-20)Carbon monoxide (CO) physisorbed on a NaCl(100) surface can undergo an isomerization reaction at cryogenic temperatures. In equilibrium conditions, the CO molecule absorbs on the surface with the C-atom closer to the Na+ ... -
Femtosecond spectroscopy of charge-transfer dynamics in self-assembled Pd(II) based donor-acceptor/host-guest cages and heterobinuclear alkyne-bridged W(II)-Ru(II) and W(II)-Ir(III) complexes
(2024-04-11)Using femtosecond UV/vis-pump-UV/vis-probe and -midIR-probe absorption spectroscopy the charge-transfer dynamics of self-assembling donor-acceptor Pd(II) coordination cages and heterobinuclear alkyne-bridged W(II)-Ru(II) ... -
Inelastic Hydrogen Atom Scattering from Semiconductor Surfaces
(2023-12-11)The adiabatic approximation is widely applied to describe interactions of atoms and molecules with solid surfaces. It assumes that the electronic system stays in the lowest-energy ground state during the interaction and ... -
Scattering of vibrationally excited NO from vanadium dioxide
(2020-01-24)This work investigates the surface dynamics of vanadium dioxide with nitric oxide in dependence of its metal-to-insulator transition (MIT) at 68 °C. At lower temperatures VO2 has a monoclinic lattice structure which has ... -
Kinetik der radikalischen Polymerisation von Monomeren mit mesogener Seitengruppe in isotroper und anisotroper Lösung
(2018-03-19)This work targets the radical polymerization of reactive mesogens in isotropic and anisotropic solution. Kinetic coefficients were determined via pulse-laser polymerization in conjunction with size-exclusion chromatography ... -
Low-Scaling Local and Fragment Self-Consistent Field Potentials in Molecular Systems
(2018-01-04)Due to the steep scaling of computational cost with increasing system size in self-consistent field calculations, approximations are required in order to make biomolecular applications amenable. Two approaches are presented ... -
Characterization of Physical and Chemical Properties of Synthetic Polymer using Ion Mobility-Mass Spectrometry
(2017-12-13)This thesis focuses on developing analytical methodologies based on ion mobility-mass spectrometry (IM-MS) for both physical and chemical properties of synthetic polymer. Beyond numerical experimental data, a comprehensive ... -
Orientation-dependent energy transfer in gas-surface collisions: Scattering of vibrationally excited nitric oxide from Au(111)
(2015-07-14)The work in my thesis is a contribution to the field of chemical dynamics at surfaces. In this field we seek to develop a detailed microscopic understanding of chemical events taking place on surfaces. Progress in ...
