This dissertation is concerned with a vibrational spectroscopic investigation of several important types of coordination compounds. As stated before, the metal-ligand vibrations are the most important in elucidating the coordination sites and the nature of the coordination bonds, and hence the investigation is focused on the low-frequency region of the spectra where the metal-ligand vibrations appear. Throughout this investigation, the new metal isotope technique has been utilized since it has been proven to be superior to the conventional techniques mentioned earlier. The coordination compounds studied in this thesis work are classified into two groups; 1) six coordinate tin (IV) halide complexes with various ligands 2) several types of the first row transition metal complexes with 8-hydroxyquinoline (or oxine).
