NMR Spectroscopy Why is it important to use a deuterated solvent? NMR uses least of this solvent They dissolve polymer the fastest Expensive solvents work best with NMR So the spectrometer can lock onto the sample to prevent the spectrum from drifting during aquisition NMR uses least of this solvent They dissolve polymer the fastest Expensive solvents work best with NMR So the spectrometer can lock onto the sample to prevent the spectrum from drifting during aquisition ANSWER DOWNLOAD EXAMIANS APP
NMR Spectroscopy Coupling causes the peaks in 1H NMR spectra to be split into two peaks multiple peaks equal to the number of hydrogen on surrounding atoms, plus one multiple peaks equal to the number of surrounding carbon atoms multiple peaks equal to the number of hydrogens on surrounding atoms two peaks multiple peaks equal to the number of hydrogen on surrounding atoms, plus one multiple peaks equal to the number of surrounding carbon atoms multiple peaks equal to the number of hydrogens on surrounding atoms ANSWER DOWNLOAD EXAMIANS APP
