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