Abstract
Vibrational spectra and normal coordinate calculations of polydichlorophosphazene (PDP) are presented. The valence force field derived previously from the two conformers of octachlorocyclotetraphosphazene was directly transferred to a distorted “cis-plan” helical model of PDP without refinement. A reasonable agreement between the observed and calculated frequencies was obtained and the assignment of the normal modes of PDP is discussed.
