NMR Spectroscopy Help


Spectroscopy problems, and in particular ones involving NMR, are an exceptionally daunting aspect of organic chemistry for most students, in part because it is such unfamiliar territory, most overwhelmed by the messy jungle of peaks and integrations on a spectrum. A rare few have the ability to reason spectroscopy problems quickly and with little analysis. This tutorial is not for such spectroscopy geniuses. This is for the other 99.9% of those who struggle with such problems, who find deciphering an NMR spectrum roughly equivalent to a kindergartner attempting to read and understand Moby Dick.

This is not a definitive guide, as there is no magic formula, no "right way" to solve for organic structures using spectroscopy. The following technique, however, broken down into 6 steps relying on common sense and a methodical approach, has proven quite effective, at least for the types of problems encountered in a standard sophomore organic course. If you don't understand the steps as you read them, the example following should make it clear as to how to apply them.

Approach to NMR spectroscopy problems:

Essentially, this technique uses:

1. the integration and IR spectrum (if applicable) to find the fragments of the compound
2. the splitting to figure out how to put those fragments together, and
3. the chemical shift to confirm the proposed structure.
