| Organic structure determination by spectroscopic methods is an integral and important component of the undergraduate organic chemistry laboratory curriculum. Students in the introductory organic chemistry course are currently introduced to the spectroscopic techniques and interpretation of IR, 1H and 13C NMR and mass spectra. The objective behind the experiment presented here is to introduce 2D NMR spectroscopy in combination with 1D NMR spectroscopy to solve an organic structural problem. The simple interpretation of COSY and HETCOR spectra is emphasized rather than the theory behind these 2D NMR experiments. A capstone experiment in the second semester organic chemistry laboratory is the identification and complete structural assignment of an unknown compound by 1D and 2D NMR spectroscopy. Students acquire and interpret the 1H and 13C NMR spectra for an unknown organic compound and they also either submit for analysis or receive copies of 2D NMR correlation spectra for the unknown compound. The combination of 1D and 2D NMR analysis allows the students to determine the structure of an unknown organic compound and to fully interpret and assign each proton and carbon signal to the organic structure. |
