  abstract  = {Structural information about the bis(benzo crown ether)s I-VI and their complexes with alkali metal cations was deduced from the 13C NMR chemical shifts, the salt-induced 1H and 13C chemical shifts and the vicinal 1H,1H coupling constants. Especially the isomerism with respect to the amide O=C - NH bonds and imine fragments were assigned by various useful NMR parameters ( C=O, 1JN,H, 1JC,H) and proved to be E,E-anti,anti. Furthermore, stereochemical information about preferred conformations about flexible bonds was obtained from 2D ROESY NMR experiments. The complex formation (2:1 complexes and sandwich-like 1:1 complexes, respectively) were determined also by 23Na NMR spectroscopy. The conformational study of the crown ethers was accompanied and corroborated by molecular dynamics and quantum chemical calculations.},

  abstract  = {Zusammenfassend konnte im Rahmen dieser Arbeit das Synthesepotential von Cyclohexadienen und Cyclohexenen deutlich erweitert werden. Die Darstellung der 1-Alkylcyclohexa-2,5-dien-1-carbons{\"a}uren erfolgte mittels Birch-Reduktion in fl{\"u}ssigem Ammoniak und anschließender Umsetzung der intermedi{\"a}r entstehenden Dianionen mit Alkylhalogeniden. So konnte ausgehend von verschiedenen Benzoes{\"a}urederivaten eine Reihe interessanter Cyclohexadiene in sehr guten Ausbeuten synthetisiert werden. Erstmals gelangen s{\"a}urekatalysierte Decarbonylierungen von Cyclohexadiencarbons{\"a}uren, was die einfache Synthese substituierter Aromaten in ausgezeichneten Ausbeuten erm{\"o}glichte. In dieser Arbeit wird der Reaktionsmechanismus vorgestellt, welcher durch den Nachweis von Kohlenmonoxid in der Gasphase der Reaktionsl{\"o}sung durch IR-Spektroskopie untermauert wird. Bei der s{\"a}urekatalysierten Umsetzung von 3-alkylsubstituierten Cyclohexadien-carbons{\"a}uren entstanden neben den erwarteten Aromaten Lactone in ca. 50\% Ausbeute. Schließlich zeigen die untersuchten Singulettsauerstoff-En-Reaktionen, der im ersten Teil dargestellten Cyclohexadiene und Lactone, durchweg hohe Regioselektivit{\"a}ten und lieferten durch elektrostatische Wechselwirkungen und konformative Effekte zum Teil sehr gute Diastereoselektivit{\"a}ten. Die auxiliarkontrollierte Photooxygenierungen von Cyclohexenon welches mit verschiedenen Weins{\"a}ureestern ketalisiert wurde, zeigten jedoch keine bevorzugte p-Facialit{\"a}t des Singulettsauerstoffs.},

  abstract  = {Electronic intensity and frequency modulation of diode lasers enables new perspectives for highly sensitive analytical in-situ techniques. For analyis of "heterogeneous" media, which may consist of coexisting gaseous, liquid, and solid phases and often show multiple light scattering, non-invasive techniques with outstanding performance characteristics can be developed. Analysis of photon density waves launched by intensity-modulated lasers provide an elegant way for the determination of absorption and scattering coefficients of multiple scattering media. The absorption coefficient can be used for qualitative and quantitative analysis of chemical constituents (which absorb in the range of the laser wavelengths). The scattering coefficient allows characterization of physical and morphological properties of the sample. In the current work, applicability of appropriate radiation transport models was investigated with simple light scattering solutions and compared with results obtained from the treatment according to the theory of Kubelka and Munk. Measurements of human blood samples are discussed. A new method for determination of water vapor partial pressure in a polyurethane foam with a frequency-modulated external cavity diode laser is discussed.},

  title     = {On the wavelength drift of spectral features from structured hot star winds},
  year      = {2001},
  abstract  = {Spectral lines formed in stellar winds from OB stars are observed to exhibit profile variations. Discrete Absorption Components (DACs) show a remarkably slow wavelength drift with time. In a straightforward interpretation, this is in sharp contradiction to the steep velocity law predicted by the radiation-driven wind theory, and by semi- empirical profile fitting. In the present paper we re-discuss the interpretation of the drift rate. We show that the Co- rotating Interaction Region (CIR) model for the formation of DACs does not explain their slow drift rate as a consequence of rotation. On the contrary, the apparent acceleration of a spectral CIR feature is even higher than for the corresponding kinematical model without rotation. However, the observations can be understood by distinguishing between the velocity field of the matter flow, and the velocity law for the motion of the patterns in which the DAC features are formed. If the latter propagate upstream against the matter flow, the resulting wavelength drift mimics a much slower acceleration although the matter is moving fast. Additional to the DACs, a second type of recurrent structures is present in observed OB star spectra, the so-called modulations. In contrast to the DACs, these structures show a steep acceleration compatible with the theoretically predicted velocity law. We see only two possible consistent scenarios. Either, the wind is accelerated fast, and the modulations are formed in advected structures, while the DACs come from structures which are propagating upstream. Or, alternatively, steep and shallow velocity laws may co-exist at the same time in different spatial regions or directions of the wind.},
