In this paper the absorption spectra of Nd-SXO-CPC complex by 4f electron tran-sitions have been studied by zero-order and fourth-order derivative spectrophotometry. The molar absorptivity is 2.6×10³ 1.mol^-1·cm^-1 at 585 nm, the fourth-order derivative molar absorptivity is 1.4×10⁴ 1.mol^-1·cm^-1 at 584.5(-) and 587(+) nm. They are 300 times and 1600 times greater than those of the chloride, respectively.
