WebSolutions of iron(III) complexes are yellow or red whilst iron(II) complexes are pale green. This is because as the oxidation state of the metal increases, Δ o increases and hence the frequency of the absorption moves towards higher frequency, i.e. for iron (III) the absorption moves towards the blue end (higher energy end) of the spectrum. WebDec 7, 2012 · The wavenumber uncertainties of lines in the FT spectra range from 10 −4 cm −1 for strong lines around 4 μm to 0.05 cm −1 for weaker lines around 1500 Å. The wavelength uncertainty of lines in the grating spectra is 0.005 Å. The ionization energy of (130,655.4 ± 0.4) cm −1 was estimated from the 3d 6 ( 5 D)5g and 3d 6 ( 5 D)6h levels.
