Abstract
The Fourier transform infrared and the Fourier transform Raman spectra of N -di-isopropylphosphorylguanidine (DPG) in the solid state and in aqueous so lution were recorded and analyzed. Assuming C-s symmetry for different stru ctural fragment of the molecule, the experimental and calculated band assig nments of the nu(NH), delta(HNH), delta(CNH), nu(C=N), nu(PN), nu(CN), nu(P O) and nu(OC) normal modes suggested that the DPC exists as a tautomeric co ntribution of the phosphorylamine (I) and N-phosphorylimine (II) structural forms.
