The next focuses on using these three techniques together to determine the structures of organic compounds. The spectrum is obtained by Fourier Transform where the time dependent FID is converted to a function of frequency, i.e., an NMR spectrum. See our Privacy Policy and User Agreement for details. A one dimensional NMR spectra has two dimensions: The x axis corresponds to the frequency axis (the chemical shifts in ppm) and the Y axis corresponds to the intensity (see the following figure). But how are frequencies encoded in a 2D experiment? For more information on these applications and the 2D NMR techniques that are used in them, please see the “Further Reading” section.
