Question

when is free Induction decay observed
​

Answer 1

Answer:

he data acquired at the NMR spectrometer is called free induction decay (FID), which is the combined decay of nuclear spins from various molecules present in the analysed sample after excitation with a short radio-frequency pulse. The FID is recorded by the spectrometer receiver as signal oscillating over time.
