Abstract:	A linear correlation between half-wave potential (E1/2) for the process M(III)→M(II) and the first d-d transition band (v) of the types cis and trans-[M(en)2X2]n+ (M=Cr(III), and Rh(III), X=ONO¯, NCS¯, F¯, Cl¯, Br¯, I¯, H2O, DMF, DMSO, n=1, 3) was found. The plots of the difference in half-wave potential (⊿E1/2) against the difference in the first d-d transition band (⊿v) for the cis and trans isomer are straight lines. The equations, E1/2=β/nαF+K1 and ⊿E1/2=(β/NαF)⊿ε were derived, and used to describe the linear correlations between polarographic behavior and electronic spectrum.
