NMR 1D Peaks Query

Macromolecule queries may take up to a minute.

Enter a list of C,N, or H peak values separated by spaces, commas, or newlines. Specify only the peak value and not the atom type. The search prioritizes entries that match the largest number of peaks first and the closeness of the matches second. Therefore you will get the best results by searching for several characteristic peaks.

Peaks are counted as a match if they are within .2 ppm for carbon and nitrogen atoms and if they are within .01 ppm for hydrogen atoms.
