摘要: The theory of double quantum transitions the ΔM=±2 type, with regard to inhomogeneously broadened spin systems is studied in this paper approximationΩ2T2T3 ≪ 1. We suppose that inhomogeneous broadening formed by an crystal field. obtained results describe magnitude absorption as a function h.f. power and also shape curve. It demonstrated curve has form difference two different Lorentz's curves at saturation (Ω2T2T1 ≫ 1) increases cube field intensity. expressed means phenomenological relaxation constants system.
