Together we are strong: A new, robust method allows the measurement of residual chemical shift anisotropies for the determination of conformation and configuration of molecules in organic solvents. The power of the method is shown by the example of estrone and 13-epi-estrone (see structures), where only the combined use of residual chemical shift anisotropies and residual dipolar couplings leads to the distinction of the two diastereomers.
