ABSTRACT:
A method and apparatus to monitor the enantiomeric excess of chiral molecules participating in a chemical reaction. The method includes real time monitoring of the chemical reaction by obtaining a VCD spectra and an IR spectra of the chemical compounds in the reaction, and manipulating the spectra to obtain a % EE value. Using such real time information, the reaction parameters can be changed to shift the reaction to produce more of one chiral molecule than another.
