The authors study a model of a heterodynamic system applied to the description of the proton magnetic relaxation of adsorbed water molecules. It is assumed that the relaxation times are determined by the spectral density of the correlation function of the stochastic motion of the molecules and that the spin dynamic is not affected by the heterodynamism. They study the proton magnetic relaxation of water adsorbed in large NaX zeolite cavities. The study of the temperature dependence of the spin-lattice, spin-spin, and proton relaxation times for this object became the basis for the Pfeifer-Gutsze-Zhdanov model.
