Definition

frequency (ISO 80000-3: Space and time) by which the nucleus angular momentum vector (ISO 80000-4: Mechanics) precesses about the axis of an external magnetic field:

ω_{N} = γ B

where

$γ$ :: is the gyromagnetic ratio (gyromagnetic ratio), and

$B$ :: is magnetic flux density (IEC 80000-6: Electromagnetism)

pulsation (ISO 80000-3: Space and time) de précession du vecteur moment cinétique (ISO 80000-4: Mechanics) d'un noyau autour de l'axe d'un champ magnétique externe:

ω_{N} = γ B

où

$γ$ :: est le coefficient gyromagnétique (gyromagnetic ratio); et

$B$ :: est l'induction magnétique (IEC 80000-6: Electromagnetism)
