WebCrystal field theory. Crystal Field Theory (CFT) is a scientific representation of how metals behave when dissolved in water to form a special type of chemical called a complex. This model may be used to predict the colors of certain metal containing chemicals when dissolved in water, as well as their reactions when placed near a magnet.

WebMay 12, 2015 · No two complexes will have exactly the same value for 10 D q. The value of 10 D q even depends strongly on the geometry: octahedral complexes have a much larger value of 10 D q than tetrahedral ones: 4.44 D q ( oct) ≈ 10 D q ( tet) The notation does not extend well to complexes in geometries other than octahedral or tetrahedral.
