The widespread practice of sharing NMR data only in processed form denies the research community the opportunity to re-examine the data or subject it to analysis using new techniques. FID is the recommended format to share primary data, cited by the ACS journals and Synthesis. Of the 223 studies included here that produced NMR data, only 3 shared primary NMR data: 1 each in an ACS journal, Synthesis, and an RSC journal.
