Questions asked by users might not always be phrased in the clearest way.
A solution if the coordination complex Na2[Co(SCN)4] has a deep blue. There are two peaks seen on the electronic spectrum. is the third peak in the uv region?
Accepted Answer
The third peak is likely in the UV region. Transition metal complexes often exhibit multiple absorption bands in their electronic spectra due to d-d transitions and ligand-to-metal charge transfer (LMCT) transitions. The two visible peaks suggest d-d transitions, which typically occur in the visible range. The third peak in the UV region could be attributed to an LMCT transition, where an electron from a ligand orbital is excited to a metal orbital.
