WebNMR Instruments Nuclear magnetic resonance spectroscopy (NMR) is an analytical technique that allows for non-invasive and non-destructive plus quantitative analytical investigations into molecular structure, dynamic processes and chemical reactions. WebThe innermost methylene protons (magenta) give an nmr signal at +22.2 ppm, and the signals from the adjacent methylene and methyl hydrogens also have unexpectedly large chemical shifts. By clicking on the above structure the dianion data will appear.
