Computation of Electronic Excitation Spectra of Large Biomolecular Systems
(2020-11-30)
This thesis presents the theoretical investigation of electronic excitation spectra and nonlinear responses of large biomolecular systems (e.g., proteins or deoxyribonucleic acid fragments), with a particular focus on the ...
Ultradünne Glasfasern als Werkzeug zur Kopplung von Licht und Materie
(2007)
Gegenstand der vorliegenden Arbeit sind ultradünne Glasfasern, die als neuartiges Werkzeug für die Kopplung von Licht und Materie eingesetzt werden. Die zugrunde liegende Idee hierbei ist, die Materie (Atome, Moleküle, ...
Investigation of the Nonlinear Optical Properties of Metamaterials by Second Harmonic Generation
(2013-11-27)
Metamaterials have attracted tremendous attention in the past decade because they allow researchers to engineer new optical properties by designing a new optical material. In particular, metamaterials are regarded as the ......
Synthesis, Crystallography and Spectroscopy of dinuclear Gold(I) NHC Macrocycles
(2015-05-11)
The synthesis, crystallography and spectroscopy of seven systematic series of dinuclear coinage metal(I) NHC complexes are shown here. As counter ions, bromide and the bulkier hexafluorophosphate are studied. Both gold(I) ...
The physical and chemical conditions of molecular clouds on large scales
(2021-09-15)
Observations of molecular emission lines in the radio and (sub)millimetre wavelength regime provide insights into the interiors of molecular clouds which are inaccessible by other forms of radiation. Examining the physical ...
Molecules in the circumstellar envelope of the evolved carbon-rich star IRC+10216
(2017-03-29)
Modern radio interferometers allow the imaging of spectral line emission over a wide range of frequencies with high angular resolution. In this thesis we present a detailed empirical examination and description of the ...
Bestimmung der Doppelpolarisationsobservablen E in der Reaktion γ⃗p⃗ → pη am CBELSA/TAPS-Experiment in Bonn
(2019-03-07)
Photoproduktionsdaten beeinflussen zunehmend unser Bild der tatsächlich in der Natur existierenden Baryon-Resonanzen. Die Analyse von (Polarisations-)Observablen ist entscheidend für die Extraktion von Resonanzen aus diesen ......
Solvatisierte Elektronen zum Abtasten der elektronischen Struktur von flüssigem Ammoniak
(2019-02-18)
Die Photolyse von reinem flüssigen Ammoniak mit ultraviolettem (UV) Laserlicht erzeugt solvatisierte Elektronen. Ist ein Elektron innerhalb einer Flüssigkeit an kein Atom gebunden, aber dennoch vom Solvens eingebettet, ......
Investigation of the Resonance-like a1(1420) Signal and First Partial-Wave Decomposition of the π -KS0KS0 Final State at COMPASS
(2024-04-26)
In 2014, a supernumerous light-meson state was found by the COMPASS collaboration. This discovery bore similarities to some of the XYZ states in the heavy-meson sector, discovered at e+e - ......
