The sets of bands in the IR and UV – spectra are the same specific a characteristic of a substance, like a person’s fingerprint. According to these spectra, the substance it can be identified if its vibrational spectrum is already known. In addition, by IR and UV –spectra determine the symmetry and structure of unexplored molecules. Frequencies the main vibrations found from the spectra are necessary for calculating thermodynamic properties of substances. Measuring the intensity of bands in the spectra allows you to quantitative analysis, study chemical equilibria and kinetics of chemical reactions, monitor the progress of technological processes. Nickel (II) ion forms many stable complexes. This work is devoted to the preparation and study of the stereochemistry of nickelphosphine complexes. We obtained nickelphosphine complexes NiBr 2 (PPh 3 ) 2 ; NiBr 2 (PCy 3 ) 2 , and analysed to determine the structure. We studied the magnetic moments of solids from the following spectra in UV-visible (electronic spectra), infrared spectrum (normal range) and far infrared spectrum.
