Magnetic circular dichroism (MCD) is a spectroscopic technique that measures the difference in absorption of left-handed and right-handed circularly polarized light in the presence of a magnetic field. This phenomenon is commonly observed in materials that have unpaired electrons and is particularly relevant in the study of transition metal complexes, rare earth elements, and paramagnetic species.
