✦ Synopsis

The i.r. spectra of bis(ethylenediamine) and bis(trimethylenediamine) complexes of Cu(II) have been measured in the wave number region of 4000-250 cm-t. Vibrational assignments have been made regarding the individual rings in both complexes. A normal coordinate analysis was performed using a modified general valence force field in order to check the empirical assignments. The agreement between the observed and calculated frequencies is satisfactory in view of the approximation used. A set of reliable force constants concerning most of the in-plane normal modes is obtained for the first time.
