Résumé : The behaviour of a paramagnetic spin system irradiated by a radio-frequency field far from resonance is studied in the frame of the theory already developed by the author. The time evolution and the equilibrium characteristics are calculated in the case of the Einbinder-Hartmann and Lee-Goldburg experiments. Theoretical and experimental results agree and the behaviour of the system may be interpreted in the case where the nonresonant character of the r.f. field modifies the usual characteristics of the evolution. © 1973.
