Right-handed enantiomers

For the right-handed enantiomer. CCDC deposition number 217979. 

For example, L and D might be the left- and right-handed enantiomers of a chiral, alcohol, and B is the ketone derived from this alcohol (see Fig. 8.15). In this cases ll studies [278] of the electronic structure of the alcohol-ketone sys tem show that there are wealdy bound chiral alcohol-ketone minima in the ground electronic state asj desired. The particular advantage of using the ketone-alcohol complex is that thfeg ketone, which is recycled after the conversion of one enantiomer to another) serves as a catalyst for the process. j x... 

An alternative way to introduce handedness into the interaction of matter witl light using linearly polarized light has been introduced by Manz, Fujimura et al [14-17]. In this approach one first preorients the racemic mixture of D and l along some axis. Under these circumstances, there is a difference in the directioi of the transition dipole moments of the left and right-handed enantiomers. Tha is, matrix elements like ( d ek Ej) are different for the two enantiomers i = L or i = L. This distinction between L and D suffices to allow for the possibility o control over enantiomers. 

D. (D-) Prefix indicating the right-handed enantiomer of an optical isomer. Usually printed as a small capital letter. 

In chemical synthesis, using chiral catalysts achieve a significant ee of either the left- or right-handed enantiomer. In these reactions, the ee of the chiral product... 

How does de lege parity violation affect chiral molecules In order to illustrate this we restrict ourselves to a two-level system with two chiral or handed states called L) and R). In classical terms these shall correspond to the equilibrimn structures of the left-handed and the right-handed enantiomer. For the quantum mechanical viewpoint we employ here for convenience the Born-Oppenheimer approximation although the discussion is also possible in quite general terms without this approximation. We assume that the ordinary — that is purely electrostatic — multidimensional Born-Oppenheimer potential energy hypersurface (PES) exhibits two minima corresponding to the left-handed and the right-handed structure which are... 

Figure 3. One-dimensional cut through a multi-dimensional Born-Oppen-heimer potential energy surface V (solid line) along the stereomutation coordinate 9 of a chiral compound, qi, corresponds to the equilibrium geometry of the left-handed, q, of the right-handed enantiomer. The corresponding parity violating potential (dotted-dashed line) has been...
