Definition

$z$ component of the diagonalized tensor of nuclear quadrupole moment:

Q = (\frac{1}{e}) \int (3 z^{2} - r^{2}) ρ (x, y, z) d V

in the quantum state with the nuclear spin in the field direction ( $z$ ), where

$e$ :: is the elementary charge (ISO 80000-1), +

$r^{2} = x^{2} + y^{2} + z^{2}$ ,

$ρ (x, y, z)$ :: is the nuclear electric charge density (IEC 80000-6: Electromagnetism), and

$d V$ :: is the volume element $d x$ $d y$ $d z$

composante $z$ du tenseur diagonalisé du moment quadripolaire nucléaire:

Q = (\frac{1}{e}) \int (3 z^{2} - r^{2}) ρ (x, y, z) d V

dans l'état quantique où le spin nucléaire est dans la direction du champ (z), où

$e$ :: est la charge élémentaire (ISO 80000-1); +

$r^{2} = x^{2} + y^{2} + z^{2}$ ;

$ρ (x, y, z)$ :: est la charge électrique volumique (IEC 80000-6: Electromagnetism) nucléaire; et

$d V$ :: est l'élément de volume $d x$ $d y$ $d z$
