Utilization Of Compounds From Undergraduate Research To Exemplify Concepts In Nmr Spectroscopy

The H-1 NMR spectra of compounds that were synthesized as part of undergraduate research projects are utilized as examples to illustrate numerous concepts that are taught in an Organic Spectroscopy course. The compounds and their spectra discussed here illustrate: Karplus curve concepts in cyclohexane rings, sigma bond anisotropy, fluorine splitting, magnetic inequivalence leading to 2nd order spectra and inverted triplets, anisotropy effects of sterically crowded aromatic rings, and the effect of hindered rotation on chemical shift. These spectra serve as excellent teaching tools.
