| Abstract |
|
Many NMR experiments in analytical chemistry courses utilize commercial Fourier transform (FT) instruments that do little in teaching the students about the components of the spectrometer. We have designed a FT-NMR spectrometer composed of self-contained components (i.e. mixers, switches, amplifiers) that has been successfully incorporated into laboratory experiments for both undergraduate and graduate students. The undergraduate instrumental analysis experiment allows students to examine the spectrometer on a component by component basis. The individual components of the spectrometer were mounted on a board and connected by coaxial cables, which easily permits changes in the configuration of the spectrometer. Topics covered in the experiment included filtering, amplification, phase cycling, and quadrature detection as well as quantitative determination of the amount of ethanol in an unknown sample. In the graduate analog instrumentation course, the graduate students were required to take the same components used in the undergraduate experiment and construct a working spectrometer.
