The Nuclear Magnetic Resonance phenomena
According to the Bohr equation,
, we need for inducing a transition towards the high level energy, an
energy quantum[1] with a value of
.
This is a resonance condition, with
which is the resonance frequency of the nucleus;
the Planck constant divided by
and
the gyromagnetic ratio.
The resonance frequency of the nucleus, which is also called the Larmor frequency, is then proportional to the field
value following the equation
.
Its range is in the high frequencies:
in a field of l.4T at the level of a frequency of
This corresponds to an ultra short radio wavelength of
.
