Journal Highlight: Minimising research bottlenecks by decluttering NMR spectra
http://www.spectroscopynow.com/common/images/thumbnails/14d0a7b07c5.jpgThe lack of resolving power in everyday NMR produces ambiguous data and causes bottlenecks, lengthening multi-step projects and increasing the likelihood of making mistakes but can be removed using pure shift techniques.
