Fig. 4. 13C{1H}-NMR spectra of racemic 1-aminoindane (molecule 4, 1 equivalent) in CDCl3 with 1 equivalent of R-VAPOL-PA added. The red closed circles indicate the peaks corresponding to each isomer and the chemical structure in the schematic shows the chemical shift difference in ppm (ΔδR/S) at the respective carbon sites.
