![]() ![]() This graph shows the decay in signal intensity (vertical axis) versus time (horizontal axis, t = 0 on left). SpinWorks remembers all of the processing that it has done and it will show you a complete spectrum, not the original FID.Īt this point, you should see a graph that looks like this: However, whenever you want to work on your spectrum in the future, you should still begin by opening the fid data file. Note: Once you transform your FID to frequency data (the next step), you will never see FID data again. Navigate to the folder that contains your NMR data To open your FID data file, do the following: The released energy is called a free induction decay or FID. Then the nuclei decay back to equilibrium by releasing radio energy. The NMR instrument creates a brief pulse of radio energy. NMR data is collected using a pulse-observe procedure.
