Theory of Multiple Resonance and ESR Saturation in Liquids and Related Media

摘要: The well-known result from the steady-state solution of Bloch equations is that absorption given by y component magnetization \(\tilde M_y\) in rotating frame(1): $$\tilde M_y = \frac{{\gamma H_1 T_2 }} {{1 + \left( {T_2 \Delta \omega } \right)^2 \gamma _e^2 \beta _1^2 T_1 }}M_0 $$ (1) with M 0 equilibrium magnetization, β1 strength rf magnetic field, and γ e electron-spin gyromagnetic ratio.
