    Notes: Zusammenfassung An Katzen in Chloralose-Urethan-Narkose konnte die nach Natriumcitrat oder Acetylcholin intracarotidal eintretende, elektrophysiologisch registrierte Erregung und vermehrte Impulsaktivität der Chemoreceptoren des Glomus caroticum und der Baroreceptoren des Sinus-caroticum durch Endoanaesthesie mit kleinen intravenösen Gaben von Dodecylnonaaethylenoxyd-aether (Do 9) unterdrückt werden.

    Description / Table of Contents: Zusammenfassung Die Lumineszenzspektren der Verbindungen Crha6J3, Crha 6 * J3 (ha* = Deuteroharnstoff), Cr3+∶Mha6J3 und Cr3+∶Mha6(ClO4)3 (M∶Al, Ga) werden bei Stickstofftemperatur und der Temperatur des flüssigen Heliums untersucht. Die Anregung erfolgt über den4 T 2-Zustand. Die Aufspaltung des2 E-Zustandes wird anhand der beiden Null-Null-ÜbergängeE 1/2→4 A 2,E 3/2→4 A 2 (Chrom-Dublett) diskutiert. Aus dem Isotopieeffekt und einem Vergleich mit IR-Messungen können die Begleitbanden als angeregte Schwingungen des Grundzustandes4 A 2 gedeutet werden. Im Mischkristall Cr3+:Gaha6J3 wird eine deutliche Aufspaltung der längerwelligen Chrom-Dublett-Bande beobachtet.
    Notes: Abstract The luminescence spectra of the compounds Cr ur6I3, Cr ur 6 * I3 (ur* = deuterated urea), Cr3+∶M ur6I3 and Cr3+∶M ur6(ClO4)3 (M∶Al; Ga) are studied at temperatures of liquid N2 and He. With the He-Ne-laser as excitation source, the4 T 2-level will be excited. The splitting of the2 E-level will be discussed. It results in two zero-phonon transitionsE 1/2→4A2;E 3/2→4 A 2. From isotope effect and a comparison with IR-data, the side bands can be assigned to the excited vibrations of the ground level4 A 2. In mixed crystalls Cr3+∶Ga ur6I3 an important splitting of the chrom dublett at longer wavelengths would be observed.

    Description / Table of Contents: Abstract Whereas 2.4 is likely to be an upper limit for the Dq/B-value of Cr(3)-complexes which show fluorescence the existence of a lower bound is rather unlikely. Experimental evidence suggests that the energy difference between the minima of the 2 E g- and the 4 T 2g-potential curves is one of the factors determining the relative intensities of phosphorescence and fluorescence.
    Abstract: Résumé Alors que 2,4 apparaît comme une limite supérieure du rapport Dq/B pour les complexes fluorescents de Cr(3), l'existence d'une limite inférieure est peu probable. L'évidence expérimentale suggère que l'intensité relative de la phosphorence et de la fluorescence est déterminée par la différence d'énergie entre les minima des courbes de potentiel des états 2 E g et 4 T 2g .
    Notes: Zusammenfassung Während 2,4 wahrscheinlich die obere Grenze für den Dq/B-Wert fluoreszierender Cr(3)Komplexe ist, gibt es für die Existenz eines unteren Grenzwerts keine Anzeichen. Experimentelle Ergebnisse legen nahe, daß das Verhältnis von Phosphoreszenz- zu Fluoreszenzemission durch die relative Höhe der Minima der 2 E g- und 4 T 2g-Potentialkurven bestimmt wird.
