Interpreting NMR spectra is a skill that often requires some amount of practice, which in turn, necessitates access to a collection of NMR spectra. Virtual Chemlab Organic has a spectra library containing more than 700 'H NMR spectra. In this assignment, you will take advantage of this by first predicting the NMR spectra for two closely related compounds and then checking your predictions by looking up the actual spectra in the spectra library. After completing this assignment, you may wish...
Draw a H NMR spectrum for each compound. Pay attention to the chemical shift (ppm) multiplicity, and integration of each peak. The boxes indicate where the peaks should go (which ppm range) as well as the relative height of each peak OH PPM O 3 PPM -2. H 10 8 PPM

Please assign structure for the compounds represented by the following NMR spectra. Integration is not needed for these simple compounds. Use chemical shift, multiplicity and your knowledge of structure to solve these easy problems. CH,Br PPM
Provide the 1H and 13C NMR data for thiophenol. Note the chemical shift, multiplicity, and integration for each (e.g. d 1.0, 3H, triplet). Clearly identify which proton is being reported and which carbon is being reported. Provide the 1H and 13C NMR data for the product generated in Question #1. Note the chemical shift, multiplicity, and integration for each (e.g. d 1.0, 3H, triplet). Clearly identify which proton is being reported and which carbon is being reported.
