This web server has been redesigned on Oct, 2015 to emphasize the importance of referencing. If your input peaks are correctly referenced according to our COLMAR HSQC Protocol, you can visit the previous version.
HSQC server has been updated to include 701 compounds.
The server will try to do a pattern matching between input peaks and peaks of some universal existing known compounds. Please examine the below plot carefully then un-check any of them that does NOT exist in your mixtures. Click "Calculate" to calculate referencing then click apply. Note that the input referencing error must be within 7.5ppm (Carbon) and 0.5ppm (Proton) for this part to work.Calculated referencing: 1H: 13C:
