What Does FID Stand For?
FID stands for Free Induction Decay
FID, or Free Induction Decay, refers to the signal produced by atomic nuclei in a magnetic field after they have been excited by a radiofrequency pulse. It is a fundamental concept in nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI), representing the decay of the induced magnetization over time as the system returns to equilibrium. Analyzing FID signals enables the extraction of structural and dynamic information about molecular systems, making it a critical component in various scientific and medical applications.
