Estimating constituents of optical isomers in mixed solution based on spin Hall effect of light
Abstract:
In this paper, an optical method for precisely estimating constituents of optical isomers (OIs) in mixed solution is presented. We convert the composition ratio of OI into polarization-rotation-dependent spin Hall effect of light (SHEL). The theoretical model between the SHEL and OI composition ratio is established in the geometrical-optics picture, and the spatial shift can be measured through weak measurement technique. Based on our theory, the concentrations of glucose and fructose in a mixed solution are separately obtained. Our accurate measurements of the chiral enantiomer composition can provide an avenue for chiral drug synthesis and analysis.

Stereoisomerism
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...
