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