CD spectroscopy provides complementary information to other analytical techniques. For example, the conformational properties and stability of peptides and proteins can be studied using CD, FTIR spectroscopy, and intrinsic and extrinsic fluorescence. Additionally, for studying biomolecule interactions, CD spectroscopy is complementary to other methods such as surface plasmon resonance (SPR) spectroscopy, fluorescence, and calorimetry (Isothermal Titration Calorimetry).
