TELLEZ, Claudio A.  and  ISHIKAWA, Dilson N.. Infrared and Raman Spectra (Solid State) of Diamminediiodidecadmium (II) Complex with ¹⁵N and ²H Isotopic Subtitution. Rev. Soc. Quím. Méx [online]. 2000, vol.44, n.2, pp.139-143. ISSN 0583-7693.

The Raman and infrared spectra of the Cd(NH₃)₂I₂ complex with 15N and 2H substitution have been obtained in the solid state. Based on a normal coordinate treatment as an eleven-body problem, the vibrational spectra were assigned. With exclusion of the ammine torsional vibration, the vibrational modes of the ligand, framework-coupling and skeletal frequencies have been determined. Valence force constants values f_CdN and f_CdI were compared with the analogous force constants of Cd(NH₃)₂Cl₂ and Cd(NH₃)₂Br₂. The results of the calculations are discussed in terms of the present assignment for Cd(NH₃)₂I₂ and previously reported potential constants for the Cd(NH₃)₂X₂ and Zn(NH₃)₂X₂ (X = Cl, Br, I).

Keywords : Infrared; Raman spectra; Diamminediiodidecadmium (II) isotopic complex; Force constants.
