The electronic absorption spectra of some pyridine derivativesiodine complexes are measured and discussed. The thermodynamic constants of these complexes are calculated. It is confirmed that the stability of the complex depends on the type as well as the position of the substituent on pyridine nucleus. A linear relationship is obtained between the enthalpies — ΔH and the shift of the blue iodine band Δv of the complexes. It is also found that as the Pi electron density on the nitrogen atom increases, the stability of the complex also increases.
