Here is a link to the Organic Structure Elucidation Workbook created by Dr. Bradley Smith, Dr. Bill Boggess, and Dr. Jaroslav Zajicek from the Department of Chemistry and Biochemistry at the University of Notre Dame.

Here their statement abou their site:

This online workbook has been developed for senior undergraduate and graduate students learning to solve the structures of organic compounds from spectroscopic data. Most problems contain an IR spectrum (film or KBr pellet), a 500 MHz 1H NMR spectrum, a 125 MHz 13C NMR spectrum, and a 70 eV electron ionization Mass Spectrum. In the 1H NMR spectra, the phrase "exchanges" means that shaking the NMR solution with D2O resulted in loss of the signal due to H/D exchange.
