Abstract

In the following the usefulness of the information that may be obtained from studies of the linear and magnetic circular dichroism of organic molecules will be demonstrated, and methods for increasing this information, especially from linear dichroism (LD), will be discussed. The LD of a sample is defined as the difference in absorbance found when linearly polarized light with the electric vectors in two directions, perpendicular to each other, is used, while the magnetic circular dichroism (MCD) is the difference in absorption of left and right circularly polarized light by a sample placed in a magnetic field.
