The paramagnetic resonance in the disordered spin systems with dipole‐dipole interactions is considered. The theory is extended into the region where βĒ ≪ 1 (β is the inverse dipole temperature, Ē is the interaction energy at the average distance between the spins). The kinetic equations are formulated and the heat capacities for real systems and the resonance form function for the Anderson model are calculated. The correlation expansion is advanced to calculate the form function and the heat capacities are calculated using the concentration expansion.
