    Notes: A new time-of-flight mass analyser compatible with conventional continuous ionization methods is described. A mass resolution at m/z 2000 of m/Δm〉2000 (50% valley) is predicted for the instrument which is presently being prototyped. Sensitivity advantages over scanning instruments are also predicted for this instrument.

    Notes: It is reported that ions gererated in the gas phase by dissociative electron attachment to nitrous oxide react with propyne-d3 (trideuteromethyl acetylene) to yield the ions ĊD=C=CH, ĊD2—C≡C-, -CD2C≡CH and CD3C≡C-. From their differing reactivity with methyl formate it is suggested that these four ions are distinct stable species.

    Notes: Low-angle light scattering, sedimentation velocity, and intrinsic viscosity measurements have been made on circular and linear forms of lambda (λ) bacteriophage DNA. Available equations, used to relate hydrodynamic parameters of both forms to the molecular weight, give relatively consistent values of particle weights which essentially agree with the light-scattering results. An average molecular weight of (34 ± 3) × 106 for λ DNA was obtained in good agreement with literature values of (31-33) × 106. The linear λ DNA has a larger root-mean-square radius than the circular molecule, when determined by light scattering, but the difference does not appear to be us large as expected from hydrodynamic data. The two forms also show significantly different angular distrbutions of scattered light intensities which agree only qualitatively with those derived from existing theory. The light-scattering results suggest that further experiments and modifications of available theories should be undertaken.

    Description / Table of Contents: The RAMAN spectrum and the IR spectrum in the range 500-4000 cm-1 of liquid 1,8,10,9-triazaboradecaline were recorded. Major frequencies were assigned by comparing the data with the IR spectra of the corresponding N-dideuterated and 10B-labeled derivatives and by taking into consideration the expected vibrational spectrum of the compound. In accordance with the PMR spectrum, the structure of 1,8,10,9-triazaboradecaline as a bicyclic B-N-C system was confirmed; the bonding situation is discussed briefly.
    Notes: Vom 1,8,10,9-Triazaboradekalin wurde im flüssigen Zustand das RAMAN-Spektrum und das IR-Spektrum von 500-4000 cm-1 aufgenommen. Durch Vergleich mit den IR-Spektren der entsprechenden N-dideuterierten und 10B-markierten Verbindung und Berücksichtigung des Erwartungsspektrums wird eine Zuordnung zu den Grundschwingungen durchgeführt. In Übereinstimmung mit dem 1H-Kernresonanzspektrum wird die Struktur der Verbindung als bicyclisches Bor-Stickstoff-Kohlenstoff-System bestätigt. Die Bindungsverhältnisse werden kurz diskutiert.

    Notes: Auf Grund magnetischer Messungen an verschiedenen Verbindungen der Elemente Th, U, Np und Pu werden die Elektronenhüllen der Elemente mit den Ordnungszahlen 89 bis 98 und ihre Einordnung in das Periodensystem diskutiert. Das Verhalten der niederen Glieder der Reihe entspricht im wesentlichen dem von Übergangselementen, das der höheren weist sie als Actiniden aus.
