    Description / Table of Contents: N.M.R. Spectroscopic Studies of 15N Labelled N-Phosphorylphosphazenes and Imidodiphosphoric Acid Derivatives15N labelled compounds were prepared and investigated by means of 31P- and 15N-NMR spectroscopy. The chemical shift values δP and δN, and the coupling constants 1JPN and 2JPP are discussed and interpreted qualitatively by semiempirical quantumchemical calculations (CNDO/2) using POPLE'S ΔE-model.
    Notes: 15N-markierte Verbindungen der Substitutionsreihen wurden synthetisiert und mit Hilfe der 31P- und 15N-NMR-Spektroskopie untersucht. Die chemischen Verschiebungen δP und δN sowie die Kopplungskonstanten 1JPN und 2JPP werden diskutiert und qualitativ mit Hilfe halbempirischer quantenchemischer Rechnungen (CNDO/2) im Rahmen des POPLE-schen ΔE-Modells interpretiert.

    Description / Table of Contents: Remarks on the Evidence of Rotational Isomers in Trichlorophosphazene-N-phosphoryl-dichloride by Means of NMR SpectroscopyBy means of 31P NMR spectroscopy no rotational isomers of trichlorophosphazene-N-phosphoryldichloride are separately observable, neither in spectra of the neat compound at the immediate range of the melting temperature nor on low temperature experiments in dimethylether solution until a temperature of 158 K.
    Notes: Mit Hilfe der 31P-NMR-Spektroskopie lassen sich keine Rotationsisomere des Trichlorphosphazen-N-phosphoryldichlorids getrennt nachweisen, weder in reiner Substanz im unmittelbaren Bereich der Schmelztemperatur noch bei Tieftemperaturmessungen in Dimethylether bis zu einer Temperatur von 158 K.
