See for yourself how ACD/Structure Elucidator Suite can solve tough structural elucidation by challenging us with your data. Our Application Scientists have accepted data for many challenging elucidations, and have achieved a success rate of 100% to date.
Complete this form to submit your data** All data received is considered confidential and will not be disclosed to any third parties without explicit permission of the submitting party. ACD/Labs reserves the right to use the Company name of participants after the successful completion of the challenge.
Minimum Required Data†
- 1H–13C HMQC, HSQC, HSQC-DEPT, HSQC-TOCSY, or HETCOR
- 1H–13C HMBC, long-range HETCOR, or LR HETCOR variants
- 1H NMR Survey Spectrum
- 1H–1H: COSY, DQF–COSY, TOCSY with short (<= 30 ms mixing time)
- Molecular formula, mass spectrum or molecular weight (MF is preferred)
† Experimental raw data is preferred over tabularized data. For large non-proprietary datasets, we will provide you with instructions on how to submit the data after the form above has been submitted.

When it comes to structure elucidation, the more information you have, the better. So if you have any of the following data please send it along as well:
- 13C NMR Simple Survey or tabularized 13C shifts, multiplicities, and intensities
- For nitrogen-containing compounds: 15N–1H HMQC or HSQC
- For nitrogen-containing compounds: 15N–1H HMBC
- IR spectrum or tabularized data
- MS spectrum or table of peaks
- Other general information, such as starting materials, related molecules (e.g., parent family of natural products), derivatives, metabolites, etc.
- TOCSY (any mixing time)
- XCORFE and other long-range Heteronuclear correlation experiments
- INADEQUATE
- DEPT, APT
- NOESY, NOE-Difference data, ROESY (depending on mixing scheme)
- Information of any impurities present in the data
