The optical activity of solutions of biological macromolecules provides information about the structural properties of the macromolecules. Circular dichroic spectroscopy (CD) is a powerful method for determining the absolute configurations and confirmations of chiral molecules. In particular, the exciton-coupled circular dichroism arising from through-space chromophore – chromophore interactions, called exciton coupling, is one of the most sensitive spectroscopic tools for.

When chiral chromophores are present, one state of circularly polarized light will be absorbed to a greater or lesser extent than the other. Over corresponding wavelengths, a circular dichroism signal can, therefore, be positive or negative, depending on whether L-CPL is absorbed to a greater extent than R-CPL (CD signal positive) or to a lesser extent (CD signal negative).

A Circular Dichroism (CD) spectrometer (also referred to as a spectrophotometer, spectropolarimeter or a circular dichrograph) is a highly specialized variation of an absorbance spectrophotometer. This spectrometer measures the difference in light absorbance between left- (L-CPL) and right-circularly polarized light (R-CPL) at multiple wavelengths when passing.

Circular Dichroism (CD) Spectroscopy. Circular Dichroism (CD) is observed when optically active matter absorbs left and right hand circular polarized light slightly differently. It is measured with a CD spectropolarimeter, which is relatively expensive (~$70k). The instrument needs to be able to measure accurately in the far UV at wavelengths.

Vibrational circular dichroism (VCD) is a spectroscopic technique which detects differences in attenuation of left and right circularly polarized light passing through a sample.

It is the extension of circular dichroism spectroscopy into the infrared and near infrared ranges. Because VCD is sensitive to the mutual orientation of distinct groups in a molecule, it provides three.
