These signals are termed free induction decay signals and they are the basic physical effect which underlies modern day magnetic resonance imaging (MRI) and nuclear magnetic resonance (NMR) experiments. Free induction decay can be described by a model developed by F. Bloch in the paper ``Nuclear Induction'' Phys. Rev. 70 (1946) 460.

In this work, the free induction decay and the SSFP signal is  Mar 1, 1980 Large-amplitude oscillations are predicted in the free-induction decay (FID) of atomic or spin two-level quantum systems that are coherently  Second-harmonic free-induction decay ina two-level spin system decay time of the FID signal signals that arise from thecoherent states induced by TP. Abstract. Purpose: To develop a framework for prospective free-induction decay ( FID)-based navigator gating for suppression of motion artifacts in carotid magnetic  We analyze the free induction decay of nuclear spins under the influence of restricted diffusion in a magnetic dipole field around cylindrical objects. In contrast to  Jun 20, 2012 We study both theoretically and experimentally the free induction decay (FID) of the electron spin associated with a single nitrogen-vacancy  Oct 25, 2012 We study, both theoretically and experimentally, the free induction decay (FID) of the electron spin associated with a single nitrogen–vacancy  Apr 26, 2010 Time-domain spectroscopy using dual, coherent frequency combs is used to measure free-induction decay from a molecular gas sample in the  Feb 23, 2018 SUMMARY. One of the primary shortcomings of the surface nuclear magnetic resonance (NMR) free-induction decay (FID) measurement is the  In Fourier transform nuclear magnetic resonance spectroscopy, free induction decay (FID) is the observable NMR signal generated by non-equilibrium nuclear   free-induction decay.

In Fourier transform nuclear magnetic resonance spectroscopy, free induction decay (FID) is the observable NMR signal generated by non-equilibrium nuclear spin magnetization precessing about the magnetic field (conventionally along z). The free induction decay of the excited slice contains spatial information, which can be revealed by Fourier transformation as in most other conventional NMR techniques. If the sample is a thin film with a thickness less than the width of the excited slice, the STRAFI image obtained in one spatial dimension is the image across the whole film.

Hahn called this signal the "nuclear induction decay" or "free induction," which today is commonly referred to as the free induction decay (FID). As described in a previous Q&A the nuclear induction signal arises as the net magnetization (M) vector precesses around the z -axis (the direction of B o).
