Amplification processes for small primary differences in the properties of enantiomers

  • Klaus Wagener
Article

Summary

Differences in the free energy of enantiomers may have two principal reasons: 1. the result of a special arrangement of external fields, or 2. asymmetric interaction due to parity-non-conservation. The effects, in general, will be very small so that an amplification is necessary in order to make them measurable. In doing so, the main problem is not to find a process of high amplification potential, but a reliable one where the obtained enantiomeric resolution is really due to differences in their properties and not an artifact caused by uncontrolled experimental parameters. Well-known cascading processes have been examined under this aspect, and two new types of amplifying processes involving solid phases and especially designed for this purpose, are described.
