Broadband decoupling is commonly used in obtaining carbon- l3 NMR spectra, and proton-proton decoupling is occasionally used to confirm coupling between protons. A simple theory of scalar coupling is covered in this chapter, which explains how the scalar coupling constant, J, can be positive, zero, or negative. It includes illustrious experiments that confirm proton-proton connectivity.
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.
