TL;DR: In this paper, the frequencies of Raman active vibrations of Mg(NH3)6Cl2 Mg (ND3) 6Cl2 in the solid state were obtained for a compound of this type.
Abstract: L'auteur a pu obtenir les frequences des vibrations actives en diffusion Raman du chlorure de magnesium hexa-ammine hydrogene et deuterie a l'etat cristallise. Toutes les vibrations attendues ont pu etre observees pour la premiere fois pour un compose de ce type (vibrations internes et vibrations externes). L'attribution de toutes les bandes du spectre est proposee. Ces resultats, rapproches de ceux obtenus par spectroscopie infrarouge, permettent de connaitre la structure vibrationnelle complete du complexe. L'eclatement de certaines vibrations montre que les coordinats ne sont pas en rotation libre et que leur orientation donne a l'ion complexe la symetrie du groupe ponctuel D3d.
The frequencies of Raman active vibrations of Mg(NH3)6Cl2 Mg(ND3)6Cl2 in the solid state were obtained. For the first time, all vibrations predicted by group theory (internal and external vibrations) were observed for a compound of this type. The bands have been assigned.
These results and those obtained using infrared spectroscopy gave a complete vibrational analysis. The splitting of certain degenerate vibrations shows that the ligands are not in free rotation and that their orientation gives the complex ion a D3d point group symmetry.

TL;DR: In this article, the Raman and infrared spectra for the complex ion complex ion were recorded and the results were primarily explicable on a point group model for complex ion ion.
Abstract: The Raman and infrared spectra (4000–40 cm) have been recorded for the salts [Pt (NH)]Cl, [Pt (NH)X]X (X = Cl, Br), mer [Pt (NH)Cl]Cl and K [Pt (NH)Cl], in the solid state. The results are primarily explicable on a point group model for the complex ion. For the monohalo and pentahalo derivatives solution Raman spectra were recorded. These indicated that solid state effects are more pronounced for the monohalo derivatives.

TL;DR: In this article, a normal co-ordinate analysis of these complex ions has been made, including all the ligand atoms, in order to check the vibration assignments made experimentally and to clarify the normal modes of vibration for the observed bands.

TL;DR: In this article, the infrared spectra of [Co(NH3)6]3+, [Co[NH3]5X]2+ (X=F, Cl, Br and I), and trans[Co[Co( NH3]4X2]- (X =Cl, Br, I) have been measured in the 4000-250 cm−1 region and the observed frequencies were quantitatively assigned on the basis of the potential energy distribution and L- matrix.
