摘要: Based on the experimental work by Boscaino et al EPR transient nutations (TNs) and free induction decay (FID) in solids, we propose modified Bloch equations (MBEs). In addition to Tomita expression for power-dependent parameter T2u, give an original phenomenological T2v tuning Δ. Both analytical (in form of a Torrey solution with these parameters) numerical solutions MBE are obtained TN different FID regimes very good agreement between theory experiment. We also discuss meaning role instantaneous diffusion mechanism pulse experiments.
