2.4. Multiple wavelengths ORD
The calculated values at different wavelengths (Table 9, Fig. S5A
supporting information) indicate a mono-signate curve down to
210 nm which can be easily and safely interpreted. The experimental
values in chloroform as solvent are obtained at four wavelengths
and are shown together with the population-weighted
calculated values (Fig. 3). The experimental values can be used for
comparison with the calculated values using methanol as solvent
since we have demonstrated that the calculated values are quite
insensitive for different solvents (see above), and the experimental
values are only slightly affected by different solvents (see above).
Calculated and experimental ORD values fit much better (Fig. 3)
with the populations derived from experimental and calculated 13C
chemical shifts compared to the pure computationally derived
populations.
