Aliasing, aka folding, is an occasionally insidious occurrence that sometimes produces unintelligible spectra. Knowledge of why this occurs, how to recognize it, and how to correct for it is critical knowledge for all instrument operators. Examples of aliased spectra and changes in the spectrometer parameters to avoid the aliasing will be presented.
When an experiment is complete, the spectrum usually shows resonances that are not all purely in phase. This section explains why that occurs and how to correct for it.
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.
