Relative Arrangement

Residual dipolar couplings (RDCs) contain information on the relative arrangement and dynamics of internuclear spin vectors in chemical compounds. The recently introduced software TITANIA implements the MFA and extracts structure and dynamics parameters directly from experimental RDCs to facilitate <i>de novo</i> structure refinement for small organic compounds. Herein, we focus on the challenges faced with experimentally inaccessible data often encountered for small organic compounds leading to voids in the RDC matrix and the concomitant effects on the structure refinement. It is shown that RDC data sets obtained experimentally from currently available alignment media and measurement methods are of sufficient quality to allow relative configuration determination even when the relative configuration of the analyte is completely unknown.<br>

Direct Use

The direct use of RDCs as restraint to construct structures based on RDCs is proposed for organic compounds. It uses the vector and dynamics information available in multi alignment data sets directly for the joint determination of conformation and configuration of organic compounds. We show that employing these data even a flat or random start structure converges into the correctly configured structure when employing multiple alignment data sets in our iterative procedure. <br>
