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.
