    Notes: [Auszug] Recent observations of infrared and microwave emission from various astronomical objects, together with their theoretical implications, were discussed at a conference held in Cambridge from July 8 to 11, 1969. This rapidly developing field of astronomy promises to contribute significantly to our ...

    Notes: Von Phenylcyanat und einigen p-substituierten Arylcyanaten wurden die Dipolmomente bestimmt und nach dem LCAO-MO-Verfahren die Doppelbindungsgrade, π-Elektronendichten und freien Valenzen berechnet. Die Substituentenkonstanten der OCN-Gruppe wurden aus der chemischen Verschiebung der 19F-Resonanzsignale von p- und m-Fluor-phenylcyanat gegenüber Fluorbenzol und aus den integralen Intensitäten der νC=C-Aromatenbanden des Phenylcyanats zu σI = +0.75 ± 0.04 und σR0 = -0.27 ± 0.07 ermittelt. Die aus den Ergebnissen abgeleiteten Schlußfolgerungen lassen Angaben über das elektronische Verhalten von Atomen der 6. Hauptgruppe zu, die von einem Aromaten und einer Nitrilgruppe flankiert sind.
