Optical yield different definitions

The fundamental scattering mechanism responsible for ROA was discovered by Atkins and Barron (1969), who showed that interference between the waves scattered via the polarizability and optical activity tensors of the molecule yields a dependence of the scattered intensity on the degree of circular polarization of the incident light and to a circular component in the scattered light. Barron and Buckingham (1971) subsequently developed a more definitive version of the theory and introduced a definition of the dimensionless circular intensity difference (CID),... [Pg.77]

Now we know that the hydroxylation of cis- and trans-2-butane yields two fractions of glycols with the same formula (CH3CHOHCCH3CHOH) but having different melting points. The two fractions formed must therefore be stereoisomers. Since their chemical properties (here m.p. s) are similar but not identical, they are not enantiomers of each other (which by definition differ only in optical rotation), but diastereomers. Note that the glycol contains two chiral centers, C2 and C3, which is compatible with diastereomer formation. [Pg.162]
