Indication from a pulsed spectroscopy experiment that takes the form of damped sine waves arising from the excited system returning to equilibrium.
Note:
In nuclear magnetic resonance spectroscopy, the FID consists of sine waves oscillating at the Larmor frequency ( ) and dampened by net dephasing time relaxation ( ), .
