Get Free Induction Decay Signal Pics. These are listed below and described in more detail in subsequent q&a's The electric signal (nmr signal) itself carries no spatial information.
Pulse Sequences And The Vector Model from chem.ch.huji.ac.il
This fid signal can be recorded. However, since the b0 has some inhomogeneity, the signal actually decays faster with the time constant t2*, which called free induction decay (fid). I understand that free induction decay (fid) signal is produced when a 90 degree pulse is given.
The fid is just one of four basic types of nmr signals produced in different ways.
The spatial information necessary to generate an image is given by magnetic field gradients that are generated by gradient coils. The resultant decay signal is termed free induction decay. It is stable to nuclear decay. The spatial information necessary to generate an image is given by magnetic field gradients that are generated by gradient coils.

The resultant decay signal is termed free induction decay. The resultant decay signal is termed free induction decay. Free induction decay (fid) nuclear magnetic resonance signal seen from a well shimmed sample. Free induction decay — n a time based electrical signal that is detected in a nuclear magnetic resonance spectrometer, that is produced by induction from the motion of the magnetic moments of nuclei, that decays with time, that can be converted to a more conventional… … Consequently in the small time interval between the two pulses, very little t1, some t2. As per my understanding this statement is not fully correct, as the free induction decay signal is acquired after the excitation pulse is turned off.
