文摘
- •
The IR/VCD spectra of crude EO were modelized as a linear weighted combination of the individual spectra of pure enantiomers.
- •
The relative percentage and absolute configuration of the major chiral compounds of EOs are obtained combining VCD and LSE.
- •
Comparing IR-LSE and VCD-LSE reveals the occurrence as a single or a mixture of enantiomers of each major chiral compound.
