Nuclear Overhauser Effect

Scalar vs. dipolar coupling is covered in this chapter, which show experiments that disprove a common misconception that there is a connection between decoupling and the nuclear Overhauser effect (NOE). A simple theory of the NOE is covered, and an experiment is presented to show how NOE experiments can be used to solve structural problems. Finally, an understanding of scalar vs. dipolar coupling shows how carbon-13 spectra can be obtained in a manner that allows for accurate integration.

Dr. Traficante obtained his Ph.D. in 1962 from MIT in the field of synthetic organic chemistry. He has worked in the NMR field since 1962, and in the early 1970s he pioneered multi-nuclear instrumentation. He has built probes, reassembled spectrometers, and developed new software programs to enhance the signal-to-noise ratio and the resolution of NMR spectra. His current research in the areas of structure determination, instrumentation, and data processing provide him with knowledge and expertise that are applicable to a broad audience. His organic chemistry background, plus his expertise in electronics, gives his lectures a special depth and appreciation for the field. Dr. Traficante is known throughout the world as an outstanding educator.
