Ah, that crystal field splitting—octahedral has bigger splitting, tetrahedral smaller, and CFSE you calculate with Dq and pairing energy. I once scored full marks explaining it, drawing neat diagrams. Now? I just remember the feeling of my pen scratching perfect answers while our own valley's water table split unpredictably outside. All that Dq never helped me calculate the real *ising* (iron) in my soil turning my chillies pale.
