I recently created a new website ( to assist chemists in identifying impurities in their proton-NMR samples. Now, when confronted with puzzling NMR resonances, chemists can narrow down the long list of potential impurities to those within a desired chemical shift range. Specifically, users input upper and lower chemical shift boundaries, select the solvent in which their sample was analyzed and receive a list of impurity peaks sorted by shift. The site uses the well-known table published by Gottlieb, et al in Organometallics. Constructive criticism is very much appreciated!
