Abstract

Abstract Gas-phase infrared spectra of polyphosphazenes (phosphonitrilic halides trimer), (NPX 2) 3 where X = F, Cl and Br have been recorded. The molecules were generated for the first time by an on-line process using solid (NPCl 2) 3 as a precursor passed over heated sodium fluoride and potassium bromide at about 550 and 700 °C for (NPF 2) 3 and (NPBr 2) 3 production, respectively. The products were characterized by the infrared spectra of their vapors. The low-resolution gas-phase Fourier transform infrared spectra reported for the first time show strong bands centered at 1295, 1215 and 1200 cm −1, assigned to ν 7( E′), in plane P N stretching mode of (NPX 2) 3, where X = F, Cl and Br, respectively.
