Optical free induction decay
Webyields the Na optical coherence decay. A beat arising from the ground-state hyperfine splitting is observed, and the results agree well with calculation. INTRODUCTION The development of optical coherence techniques for prob-ing the properties of systems of atoms and molecules has in many instances closely followed the path of development WebOct 14, 2024 · Free induction decay (FID) refers to a short-lived sinusoidal electromagnetic signal which appears immediately following the 90° pulse. It is induced in the receiver coil by the rotating component of the magnetization vector in the x-y plane which crosses the coil loops perpendicularly. It does not contribute to MR image but is used for single ...
