Dialysis dialysis is the separation of components in a mixture by passing them across a semipermeable membrane. I • I I diamagnetism diamagnetic. Compare with paramagnetism. Diamagnetic materials are very weakly repelled by magnetic fields. The atoms or molecules of diamagnetic materials contain no unpaired spins. I • I : ~ ; : I I diastereomers diastereomers are stereoisomers that are not related as mirror images. The term is equally valid for both 3D and 2D molecules. Diastereomers differ in both their physical and chemical properties.
