Abstract

Abstract: The effect of rare earth ion Eu³⁺ on hemoglobin(Hb) was studied by using two dimensional Raman correlation spectroscopy. The results show that with the variation of Eu³⁺ concentrations as perturbation, the oxidation state of Hb and its spin state are both sensitive to the perturbation. Eu³⁺ added to Hb affects the oxidation and spin state synchronously. The four structure sensitive bands of Hb are more accessible to the Eu³⁺ than other bands.

Key words: Rare earth ion, Hemoglobin, Oxidation state, Spin state, 2D Raman correlation spectroscopy
