Section: Module 6: Lesson 2: NMR Spectroscopy | Organic Chemistry 2 | NextGenU.org

  • Student Learning Outcomes:
    Upon completion of this module, students you will be able to:
    • Explain the main principles and features underlying NMR spectroscopy.
    • Explain how a typical continuous wave spectrometer operates.
    • Appraise the reasons responsible for the difference in behavior observed in NMR experiments for the proton nuclei of compounds.
    • Determine key regions and peaks within an NMR spectrum.
    • Interpret proton chemical shifts associated with different functional groups.
    • Gauge the influence of hydrogen bonding and solvent effects on NMR chemical shifts.
    • Distinguish spectral information from solvent and standard reference NMR signals.
    • Explain how upfield and downfield directions relate to chemical shift (ppm) on the H-NMR spectrum.
    • Apply the n+1 rule to estimate the number of neighboring protons based on the number of peaks on the H-NMR spectra.
    • Correlate deshielding and spin-spin coupling to changes in NMR spectra.
    • Explain the reason for doublet, triplet, and quartet coupling patterns (both multiplicity and intensity).
    Approximate time required for the readings for this lesson (at 144 words/minute): 2 hours and 45 minutes.
