Spectral Database for Instructors

Andrew Harned’s group in Minnesota has put up a site on spectral database for instructors. It would be useful for any chemist if they wanted to find the FID for any NMR spectrum of a compound they are trying to make.  I think this would be actually a good idea to have for any compound in general as proof of compound synthesized.  It would be nice if we don’t have to be instructors to use it though.
