FIR.-Spektren von Übergangsmetallkomplexen mit orthogonalem Ligandensystem. I. Halogeno-Kupfer(II)-Komplexe methylsubstituierter Pyridine

Far-infrared spectra (400–40 cm^?1) have been studied for orthogonal systems CuL₂X₂ (L = pyridine, mono-, di-, tri-methylsubstituted pyridine and X = Cl, Br). Assignements are suggested for the four bands of the molecular vibrations which form a stable region within the spectra of the complex series. Relations between number and position of bands and structural data are discussed.
