- The energy gap is the crystal field splitting energy _.
- Therefore, the one electron is in a low energy orbital.
- For Ti3+, the gap between energy levels, _ is of the order of the wavelength of visible light.
- As the [Ti(H2O)6]3+ complex absorbs visible light, the electron is promoted to a higher energy level.
- Since there is only one d electron there is only one possible absorption line for this molecule.
- Color of a complex depends on the magnitude of _ which, in turn, depends on the metal and the types of ligands.
