CREATING NMR SIGNALS

As stated earlier, when placed in a magnetic field, the hydrogen nuclei adopt one of two different orientations, aligned either with or against the [Pg.20]

Deuterium ( H) is the most common lock signal. H, Li, and F have also been employed for this purpose. Can we use a nucleus as lock signal while recording a spectrum of the same nuclei  [Pg.21]

For a transition to occur from the lower energy state to the upper energy state, the precessing nuclei must absorb radiofrequency energy. This can happen only if the radiofrequency of the energy being emitted [Pg.21]
