Explain spectrochemical process...??
Answers
According to the spectrochemical series, H2 O is a weak-to-medium-field ligand. Here, Co is in a +2 oxidation state with 7 d electrons. Because H2 O is not strong enough to force electrons to fill the t2g first, the configuration is t2g5, eg2. This is a high-spin complex with 3 unpaired electrons.
➡Spectrochemical analysis is one of the major tools of analytical chemistry.
➡Spectrochemical analysis employing optical spectroscopic methods is used to monitor the water we drink, the food we eat.
➡Spectrochemical methods usually measure the electromagnetic radiation produced (emitted) or absorbed by molecular or atomic species of interest. It has to be added though that spectroscopy nowadays includes some methods that do not involve EM radiation, such as acoustic and mass spectroscopy.
