What is Free Induction Decay in NMR?
Hello I will give you a basic run down of what these two things meen. Then a couple of ideas of there applications. Nuclear Magnetic Resonance = NMR Free Induction Decay = FID Very basic the FID is the acctual measurement of the NMR. If you web search FID+NMR you will get many great related articles for univeristies all over the world. It is used in chemisrty as well as bioligy and magnetic resonance Now for a dictionary explanation. In Fourier Transform NMR, a free induction decay (FID) is the observable NMR signal generated by non-equilibrium nuclear spin magnetisation precessing about the magnetic field (conventionally along z). This non-equilibrium magnetisation is generally created by applying a pulse of resonant radio-frequency close to the Larmor frequency of the nuclear spins. If the magnetisation vector has a non-zero component in the xy plane, then the precessing magnetisation will induce a corresponding oscillating voltage in a detection coil surrounding the sample.
