Circular dichroism

{
  "id": "MLC-T-CHM-002082",
  "term": "Circular dichroism",
  "field": "Chemistry",
  "definition": "The differential absorption of left and right circularly polarized light by a chiral substance, resulting in a measurable spectroscopic signal. This phenomenon occurs when a molecule possesses optical activity and absorbs light in a specific wavelength range. Circular dichroism spectroscopy is widely used to determine the secondary structure of proteins and the absolute configuration of chiral molecules.",
