Chiral hydrindanon
WebAn amino acid has the general formula H₂N-CH (R)-COOH, where R stands for the different acids. Notice that the central C atom is chiral — it has four different groups attached — so the molecule can exist as a pair of enantiomers (nonsuperimposable mirror images). One of these is the D isomer, and the other is L (i.e. a pair of R/S isomers). WebA chiral medium exhibits different complex refractive indices for those two polarization states . The difference in the imaginary part results in a different absorption of RCP and LCP light, which is called circular dichroism (CD). A linearly polarized light field, on the other hand, will be rotated with respect to its original orientation ...
