Paper Abstract

The polarity and polarizability of -P=N and P-X bonds in phosphazenes (NPX2)n are influenced by the structure and effective electronegativities of the ligands (X) attached to the phosphorus atoms. The nature of chemical bonding in phosphazenes is revealed through responses of vibrational spectra to perturbations such as external pressure and solvent-hydrogen bonding, as well as chemical and isotopic substitution of the ligands. Raman spectra of a series of cyclic phosphazenes are used to identify and classify the vibrational modes. Changes in vibrational frequencies and Raman intensities are interpreted in terms of the polarized chemical bonding model suggested by recent calculations.
