NMR Spectroscopy Why is it important to use a deuterated solvent? NMR uses least of this solvent So the spectrometer can lock onto the sample to prevent the spectrum from drifting during aquisition Expensive solvents work best with NMR They dissolve polymer the fastest NMR uses least of this solvent So the spectrometer can lock onto the sample to prevent the spectrum from drifting during aquisition Expensive solvents work best with NMR They dissolve polymer the fastest ANSWER DOWNLOAD EXAMIANS APP
