Abstract: Kinetic equations for the one-particle spin density matrix for a system of magnetic molecules in a liquid interacting with one another through intermolecular spin-spin forces are derived under the following assumptions: a) “internal” relaxation processes are ignored: b) at t = 0 the entire density matrix is factorized,σ(0) = Π1σ1(0), σ(0) being the spin density matrix of the matrix of the with molecule; c) random motions of particles in the liquid are considered as a classical markovian process. The finite set of integrodifferential equations, with rank equal to the number of different kinds of the molecules, is obtained for the matrices 〈σ1(t)〉 averaged over all the possible trajectories of the molecules in the liquid.
