Raw data of the resonance linewidth, the signal intensity, the noise intensity, and the sensitivity each as a function of ω ₁. T ₂₀ is the transverse relaxation time which is obtained by measuring ϕ ( t ) as a function of ω ₂ when ω ₁ is much smaller than ( T ₁ T ₂)^−1/2, and T ₁₀ is the longitudinal relaxation time which is assumed to be a constant. (a) Experimental (asterisks) and computational (solid line) results of the resonance linewidth; (b) experimental (asterisks) and computational (solid line) results of the signal intensity; (c) experimental results of the noise intensity; (d) experimental results of the sensitivity.
