Notes:
Assignments are proposed for the IR and Raman spectra of potassium, zinc and mercury(II) nicotinates and for the UV-visible spectra of the f → f transition for erbium nicotinate. The influence of K, Zn, Hg(II), Nd(III), Dy(III) and Er(III) on the aromatic system of nicotinic acid was studied. There are essential differences in the number, wavenumber and intensity of aromatic system bands in the ranges of the ring modes, (1610-1400 cm-1), γ(CH) (970-700 cm-1) and Φ(CC) (700-650 cm-1), depending on the central ion. Potassium and mercury(II) perturb but lanthanides stabilize the aromatic system of nicotinic acid. The wavenumbers and intensities of some vibrational bands of the aromatic system depend systematically on the ionic potentials of the metals.
