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

†If you are a Shimadzu customer or intend to import Shimadzu data, check if any Shimadzu software has already been installed on the same computer prior to installing any of the ACD/Labs mass spectrometry packages. Problems can occur if both are installed on the same computer. For further assistance, please contact ACD/Labs Technical Support.
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
