Confirm the export is 1H or 13C from Bruker, JEOL, Varian or JCAMP-DX. Re-export from the processing software rather than sending an unnamed binary. If the family is different, contact us instead of assuming support.

The shortlist looks implausible

1. Check referencing and solvent.
2. Confirm you submitted both nuclei if you have them.

4. Decide whether the case is a mixture.
5. Compare 13C RMSD across the top analogues.
