Popis: The Fourier transform infrared and the Fourier transform Raman spectra of N-di-isopropylphosphorylguanidine (DPG) in the solid state and in aqueous solution were recorded and analyzed. Assuming Cs symmetry for different structural fragment of the molecule, the experimental and calculated band assignments of the ν(NH), δ(HNH), δ(CNH), ν(C N),ν(PN),ν(CN), ν(PO) and ν(OC) normal modes suggested that the DPG exists as a tautomeric contribution of the phosphorylamine (I) and N-phosphorylimine (II) structural forms.
