(iv) In transition metal complexes such as those in part (a)(i), what determines the wavelength of light absorbed. (v) Using the answers to (a)(i) to (a)(iv), explain why: • • The colour arising from d-d transitions in [Fe(OH₂)61³ is less intense than that arising from d-d transitions in [Fe(CN)]³. [Fe(OH₂)] absorbs light at a longer wavelength than [Fe(CN)]¹.
