The structural elucidation of molecules is a core component of undergraduate organic chemistry coursework. Accordingly, most introductory organic lab classes give students the opportunity to employ basic proton and carbon-13 NMR techniques. At the present time, two-dimensional NMR techniques, which provide more information and thus may be used to determine the structure of complex molecules, are absent from the curriculum. In order to evolve with the new liberal arts programs that utilize increasingly available 60 MHz benchtop instruments, we have developed a series of experiments designed to give hands-on experience of 2D techniques. Students are asked to acquire and interpret the 2D spectra of a number of unknown compounds, chosen due to their easily visualized spectra, in order to ascertain their molecular structures. Our poster will provide details of these experiments and illustrate the spectra obtained.
