Decoupling techniques remove the splitting of signals due to heteronuclear interactions (e.g., ^1H-^13C). This simplification clarifies spectra, making it easier to assign peaks to specific atoms within a molecule. Dynamic Nuclear Polarization (DNP) DNP enhances NMR signal strength by transfer...
Print the region from 10 ppm to 0.5 ppm for every spectrum you take. 1. Draw the expected structure on the spectrum, and label it with your notebook page number. 2. Number the hydrogens on your drawing and assign them (with labels) to the peaks in the spectrum. ...
