Figure 6.

(A) Comparisons between measured spectra of R5a attached to mixed diastereomers (solid orange lines) and those computed by weighted average of the individual R_p- and S_p-R5a spectra (dashed black lines). All spectra were measured at 5°C. (B) An example of a mixed-diastereomer spectral simulation. (C) Comparisons of motional parameters obtained from fitting experimental spectra of mixed diastereomers (open bars), R_p (gray bars) and S_p (black bars). Weighted averages of R_p and S_p parameters (hatched bars) are also included.
