Intra-molecular enantiomerism in R-(+)-Limonene as evidenced by the differential bond polarizabilities.
We propose an algorithm to obtain the differential bond polarizabilities from the Raman and Raman optical activity (ROA) spectral intensities. The signs of the differential bond polarizabilities of R-Limonene demonstrate that there is intra-molecular enantiomerism in its six membered ring structure. That is, the signs of the differential bond polarizabilities around the six membered ring are inversed under an intra-molecular mirror reflection. This is similar to what happens in the right and left handed chiral isomers under a mirror conversion.
