Consider the nuclei in the absence of any spin-spin splitting. 3. 4, Describe the effect of the magnet's power, Bo, on the chemical shift (: ppm spectrum)? Explain

Explanation / Answer

The Bo field created by magnet actually contains a broad band width of frequencies that excite all the nuclei in a molecule at the same time, and the net magnetization along the y-axis is the sum of the magnetization of each set of equivalent nuclei, all precessing at different frequencies. The resulting complex waveform is called the free induction decay (FID) or the time domain spectrum. It is a measure of y-axis magnetization My as a function of time after the Bo pulse.
