    Scanning laser acoustic microscope with digital data acquisition (1987)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 58 (1987), S. 45-53

    Notes: A scanning laser acoustic microscope (SLAM) is described. The SLAM achieves a resolution of about 10 μm and is capable of imaging subsurface features at depths up to several millimeters, using appropriate reconstruction algorithms. The various components of the apparatus, both acousto-optical and electronic, are described. A major feature of the SLAM is a digital data-acquisition system capable of storing and processing the complex acoustic field in images with 256×256-pixel resolution. An array processor enables most floating-point operations to be completed in a few seconds. Examples of acoustic images obtained from a test sample are presented.

    Measurement of the rotational spectra of OH+ and OD+ by laser magnetic resonance (1986)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: Far IR rotational transitions between the four lowest rotational levels in the X 3Σ− vibronic ground states of OH+ and OD+ have been observed by laser magnetic resonance spectroscopy. Ground state molecular constants, including the three g factors, have been determined and employed in the calculation of a Born–Oppenheimer equilibrium geometry. The centrifugal distortion of the spin-rotation interaction is found to have a significant effect on the determination of other molecular constants. Hyperfine splittings have been resolved and analyzed for OH+, but could not be observed in OD+ spectra with a 6 MHz collision-broadened linewidth.

    Measurement of the rotational spectrum of the water cation (H2O+) by laser magnetic resonance (1986)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 85 (1986), S. 1252-1260

    Notes: Nine rotational transitions of v=0 X˜ 2B1 H2O+ have been measured by laser magnetic resonance. Optical combination differences have been combined with the LMR data in a weighted least-squares analysis using a Watson S-reduced rotational-fine structure Hamiltonian. Twenty-four molecular constants were simultaneously determined, including three hyperfine parameters and the axial components of both the anisotropic and rotational g tensors. The anisotropic g tensors are compared with their calculated values using the Curl relationship. An r0 structure was determined and is in good agreement with several ab initio results.

    Description / Table of Contents: The viscosity level in the range of the Newtonian viscosity η0, as well as in the shear rate dependent range (non-Newtonian-viscosity, η = f(\documentclass{article}\pagestyle{empty}\begin{document}$$ \mathop \gamma \limits^. $$\end{document})) of polymer solutions can be determined on the basis of a molecular modelling. Prerequisite is the information about the molecular parameters of the individual molecules  -  found in most cases in handbooks  -  and the result of the one-point measurement of η0 in the concentrated range.In addition, a criterium for shear stability was obtained, predicting the boundary range between a stable and a degraded polymer solution. This criterium holds for the laminar as well as for the turbulent flow. So, answers could be given to technologically interesting questions about the stability of the solutions.Under modified considerations, these results may be applied to polymer melts.
    Notes: Das Viskositätsniveau im Bereich der Ruhescherviskosität η0 (Newtonscher Bereich) sowie im schergeschwindigkeitsabhängigen Bereich (nicht-Newtonscher Bereich (η = f(\documentclass{article}\pagestyle{empty}\begin{document}$$ \mathop \gamma \limits^. $$\end{document})) von Polymerlösungen kann auf der Basis molekularer Modellierungen bestimmt werden. Voraussetzung hierfür ist die Kenntnis der molekularen Parameter des Einzelmoleküls, welche in vielen Fällen Handbüchern entnommen werden könen, und das Ergebnis einer Einpunktmessung von η0 in konzentrierter Lösung. Darüber hinaus wurde ein Stabilitätskriterium erarbeitet, das den Grenzbereich zwischen einer scherstabilen und einer degradierten Polymerlösung vorhersagt. Dieses Kriterium ist sowohl für den laminaren als auch für den turbulenten Strömungszustand verwendbar, wodurch anwendungstechnologisch bedeutsame Fragestellungen bezüglich der Stabilität beantwortet werden können.Die Ergebnisse sind unter einer modifizierten Betrachtungsweise auf Polymerschmelzen übertragbar.
