Problem of the month
More challenging examples
Picture of a FID


Inspired by Nils Schlörers "Problem of the month" this problem set tries to focus on some topics that require a little bit more in the way of description or explanation. These include isotope patterns, chirality, deceptively simple spectra, complex multiplet patterns, unexpected magnetic inequivalency, and more.

Additional notes on data protection

If you dive into the examples on this page with something other than a touch device (e.g. a desktop computer) an external service provided by Microsoft is used. As a consequence, this provides Microsoft with information about the browser you are using, your location, and the time of your access. If, for any reason, you do not want this to happen please use the homepage of this project to view the spectra. There another, Microsoft-independent, way to display the detailed content of each problem set is used.

Using tablets or cellular phones to browse through the individual problem sets doesn't use third party services.
