Example NMR Spetrum (Fossil Resin) |
The M100 NMR spectrometer is used primarily for the characterization of carbon-13 functional groups in solid-samples. The example to the right is a spectrum taken from a fossil resin. Observed resonances include those indicative of carbons in double bonds (carbons 8-17 and 12-13; 149-107 and 136-126 ppm, respectively), carboxylic acid groups (carbon-19; 186, 181 and 177 ppm) and aliphatic carbons, which range between 70 and 10 ppm. Bulk characterizations and structural elucidation studies can be carried out using this technique. |

This analysis required 10 hours of acquisition time and approximately 100 mg of sample. Roughly 10,000 transients were collected. Details can be found in Clifford et. al (1998). |
