In Review Interpreted NMR Data Scott Van Bramer Department of Chemistry, Widener University, Chester, Pennsylvania, 19013 svanbram@science.widener.edu Abstract: A large number of NMR experiments are used for structural determination. For students to learn which experiment is appropriate, they need to understand what type of information is provided by each technique. This paper uses web based visualization tools to explain how the information provided by NMR techniques fits the molecular structure. The experiments here include; proton, selective homonuclear decoupling, carbon (decoupled), carbon (coupled), carbon (gated decoupling), carbon (inverse gated decoupling), DEPT, APT, COSY, NOESY, HETCOR and T₁ inversion recovery. These spectra as used examples for teaching Advanced Spectroscopy at Widener University. Readers are encouraged to consult the references for additional information about the experimental techniques.
