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