Abstract

Differential circularly polarized light spectroscopy
Definition
Molecules that cannot be superposed on their mirror images are known as “chiral,” from the Greek word χειρ. Examples of chiral molecules are given in Fig. 1. A molecule is achiral (i.e., not chiral) if it has a reflection plane or inversion center, so its mirror image can be rotated round to look exactly like the starting molecule. Circular dichroism (CD) is the difference in absorption of left and right circularly polarized light (Cantor and Schimmel 1980; Craig and Thirunamachanrdan 1984; Michl and Thulstrup 1986; Rodger and Nordén 1997; Barron 2004; Nordén et al. 2010).
