NMR Mosaic Student Page

Solving 1H NMR is an important skill which takes practice to learn. It is a very logical process, but is difficult for most students for two major reasons:

  1. There are three different types of information present in the spectrum and it is easy to forget to use one of them.
  2. Once you have the molecular fragments from the spectrum, it can be difficult to see exactly how they all fit together.
This makes it all too easy to make mistakes.

The NMR Mosaic was designed to help you master 1H NMR interpretation. It helps you remember to use all three types of information in the spectrum because you need them all to put each mosaic piece together. 

Better yet, it helps you find the correct structure in several ways. First the colors help you visualize the connectivity that is encoded in the 1H NMR spectrum. Second the mosaic will help you recognize incorrect interpretations because the mosaic pieces will not all fit together if something is wrong. Finally, it can help you interpret "evil" spectra which contain complex multiplets where it is virtually impossible to figure out how many hydrogens are spitting the peak. 

Some of my students have even said that using the NMR Mosaic even made solving NMR spectra fun!
