About This Quiz & Worksheet

Check to see how much you know about the theory of NMR spectroscopy with this multiple-choice quiz and worksheet. For instance, you should understand why it's necessary to add additional milligrams of a substance with a high molecular weight to an NMR sample.

Quiz & Worksheet Goals

You'll be tested on the following:

  • The purpose of centrifuging an NMR sample in an NMR tube
  • Collecting carbon-13 NMR spectra when decoupled from Hydrogen-1 nuclei
  • Adding milligrams of a substance with a high molecular weight to an NMR sample
  • Why C spectra requires a higher sample concentration
  • Integrating the area beneath an absorption peak

Skills Practiced

  • Interpreting information - verify that you can read information about centrifuging an NMR sample in an NMR tube and interpret it correctly
  • Making connections - use what you've learned to make connections between carbon-13 NMR spectra and Hydrogen-1 nuclei
  • Information recall - access the knowledge you've gained about the area beneath an absorption peak
