jee-mainjee-advancedneet-ug
Partially filled d → d-d excitation; observed colour is complementary to absorbed
What each symbol means
| Symbol | What it stands for |
|---|---|
| hν | Photon absorbed in visible region |
| ΔE | Crystal-field / ligand-field splitting energy gap |
When to use this
Requires incompletely filled d subshell; d⁰ and d¹⁰ often colourless in simple aqua ions (exceptions with LMCT exist).
