Questions asked by users might not always be phrased in the clearest way.
Tetrahedral complexes typically exhibit transitions at shorter wavelengths and lower intensities compared to octahedral complexes. This is because tetrahedral complexes have a lower symmetry, leading to weaker ligand field splitting and smaller energy differences between d-orbitals. Consequently, the electronic transitions require higher energy photons, resulting in absorption at shorter wavelengths (higher energy). The lower symmetry also contributes to the weaker intensity of the transitions.
