The solution reaction mechanisms,composition,donor atoms,properties of coordinate link and stability ofthe complexes on the systems of adrenaline with Na~(3+),Gd~(3+)and Tm~(3+)have been studied by pH-potentiometrictitration and electronic spectroscopy.Adrenaline perturbs the f-f electronic transition of Nd~(3+)and Tm~(3+)sothat the absorption spectra of their complexes are shifted toward longer wavelengths.The absorption spectra ofthe complexes formed by the three f-block element ions with adrenaline are shifted toward shorter wavelengthswith the increase of PH in Δγ=350～650 nm The solution reaction mechanisms, composition, donor atoms, properties of coordinate link and stability of the complexes on the systems of adrenaline with Na ~ (3 +), Gd ~ (3+) and Tm ~ (3+) have been studied by pH- potentiometrictitration and electronic spectroscopy. Adrenaline perturbs the ff electronic transition of Nd ~ (3+) and Tm ~ (3+) sothat the absorption spectra of their complexes are shifted toward longer wavelengths. The absorption spectra of the complexes formed by the three f-block element ions with adrenaline are stepping into the short wavelengths with the increase of PH in Δγ = 350 ~ 650 nm
