Preferred Label : circular dichroism;
Detailed label : circular dichroism (CD);
IUPAC acronym : CD;
IUPAC definition : A spectroscopic method which measures the difference in absorbance of left- and right-handed
circularly polarised light by a material, as a function of the wavelength. Most biological
molecules, including proteins and nucleic acids, are chiral and show circular dichroism
in their ultraviolet absorption bands, which may be used as an indication of secondary
structure. Metal centres that are bound to such molecules, even if they have no inherent
chirality, usually exhibit CD in absorption bands associated with ligand-based or
ligand-metal charge-transfer transitions. CD is frequently used in combination with
absorption and i MCD /i studies to assign electronic transitions.;
