Useful Tips for 1D and 2D NMR Experiments

Qualitative Analyses of Mixtures:  I have primarily done mass spectrometry during my career, but also utilize NMR data in conjunction with mass spectrometry data to identify components.  Often even relatively complex mixtures can be characterized by 1D and 2D NMR data utilizing complimentary information obtained by either LC-MS or GC-MS analyses.

Quantitative Analyses of Mixtures:  In addition, a mixture sample can be used to generate a secondary standard for GC, LC, GC-MS, LC-MS, etc. using quantitative NMR with an internal standard.

Laura Adduci shared with me a very useful NMR presentation of tips, tricks, and techniques.  Laura currently works in our NMR laboratory at Eastman Chemical Co., but prepared the presentation while attending UNC-Chapel Hill.

We also utilize both carbon and proton NMR for quantitative analyses.  It is a very powerful approach because standards are not required to calibrate the instrument response.  All that is required is that the component or components of interest be correctly identified.  I have included three links below that I have found very useful for quantitative NMR analyses:
