    Description / Table of Contents: 13C-NMR-Spektren von CyclopeptidalkaloidenEs werden die 13C-NMR-Spektren von Zizyphin-A (2), Amphibin-D (3), Amphibin-E (4) und Zizyphin-D (5) studiert und die Ergebnisse im Zusammenhang mit der vorliegenden Konjugation in der Alkoxystyrylamin-Einheit betrachtet.
    Notes: The 13C-NMR spectra of four cyclopeptide alkaloids, namely zizyphine-A (2), amphibine-D (3), amphibine-E (4), and zizyphine-D (5), have been studied. Conclusions have been drawn concerning the conjugation in the alkoxystyrylamine unit present in these compounds.

    A simple method for calculating x-ray absorption spectra for use in crystal spectrometer and mirror analysis (1982)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: A simple scheme is described whereby x-ray absorption spectra, including the very strong rapidly varying structure near an absorption edge, may be calculated using only a short program and small amounts of computer time. The analysis also provides general rules for the existence of strong structures at the edge. The scheme can describe any neutral absorbing atom (or, with a little modification, ion) and includes the effect of the core hole when necessary. Fits to experiment show good agreement near absorption edges, with somewhat poorer agreement far from the edge. The method is of use in obtaining absorption spectra for use in crystal spectrometers for x-ray mirror calculations where a knowledge of the fine detail of the absorption is not necessary, but an accurate reproduction of the major structure near the edge is.
