N2 - Vibrational spectra of Li+, Na+, K+, Rb+ and Cs+ nicotinates, benzoates, salicylates and p-halogenobenzoates have been studied. Characteristic changes of spectra within the regions: 1610-1380 cm-1 [v(C-C)ar, vasym(COO-) and Vsym(COO-)], 1360-1000 cm-1 [β (C-H)], and 970-740 cm-1 [γ (C-H)] have been observed. The effect of metal on different ligands (benzoic, salicylic, and nicotinic acids) has been compared. The linear correlations between changes of the wavenumber of selected bands and the ionic potential as well as electronegativity of cation have been found. Ionic potential and electronegativity of the metal and halogen are the main factors responsible for perturbation of uniform electronic charge distribution in the aromatic ring in case of all ligands.
