The time irreversible evolution of a two-nucleus spin system interacting with a magnetic field is analyzed in the framework of the subdynamics theory. The spin system is determined by the H(1), C(13) nuclei. The investigation is based on the complex spectral representation of the Liouvillian which gives a rigorous description of irreversibility. The evolution of the density matrix is analyzed for the short and long time region. Quantum Zeno effect is discussed.
