16 Δεκ 2021 · As seen in the 1 H NMR spectrum of methyl acetate (Fig. 6.6a), the x-axis units of NMR spectrum are in ppm (not in Hz as we would expect for frequency), and the two signals stand at different position along the x-axis. Let’s explain how that works and what information can be obtained.
A GUIDE TO 1H NMR CHEMICAL SHIFT VALUES. Nuclear Magnetic Resonance (NMR) is a commonly used technique for organic compound structure determination. In 1H NMR, applying an external magnetic field causes the nuclei spin to flip.

Numclear magnetic resonance (NMR) is particularly useful in the identification of the positions of hydrogen atoms (1H) in molecules. This is an invaluable technique in the identification of organic compounds and commonly used in analytical laboratories.
There are generally three possible ways for aromatic peaks to appear in a H NMR spectrum when only one group is attached the ring. STRONG DEACTIVATING GROUPS have a partially positive atom attached directly to ring. These include C=O, NO2, CN and S=O groups. This often produces a split into two peaks, centered at around 7.6 ppm.
