Quantized nuclear spin • Nuclear spin is a form of angular momentum

• Nuclear spin, I , is quantized in units of ℏ

• Nuclear quantum number depends on nuclear configuration; I=1/2, 1… • Hydrogen has spin I=1/2, with spin projection numbers m I =+1/2 , -1/2; spin ‘up’ or ‘down’

• Magnetic moment is μ =γ I
