For the general case of a nucleus of spin value /, Xo = 3IkT □ (133) 2.4

because the interaction is usually small it is permissible to distinguish between

spin temperature and lattice temperature. However, the small interaction does

enable thermal equilibrium to be established eventually between the two systems

. The resultant temperature will be close to that of the lattice since the heat

For the general case of a nucleus of spin value /, Xo = 3IkT □ (133) 2.4

**Spin**-**Lattice Relaxation**Nuclear spins invariably interact with their surroundings butbecause the interaction is usually small it is permissible to distinguish between

spin temperature and lattice temperature. However, the small interaction does

enable thermal equilibrium to be established eventually between the two systems
