Simulated trajectories of S_zI^β operator during the mixing period when only the S³E element (green), only the S³CT (blue), both S³E and S³CT elements (red), and no S³E or S³CT elements (cyan) are included in the pulse sequence of Figure 1. The black line represents a mono-exponential function with the decay rate equal to R̄₁−η _z. The relaxation parameters used for the simulations are the following: R_1H = 2.5 s⁻¹; R_1N = 1.8 s⁻¹; R_1HN = 3.8 s⁻¹; η_z = 1.2 s⁻¹; η _H = 1.0 s⁻¹; σ = 0.03 s⁻¹. A rotational correlation time of 10 ns was used to estimate the relaxation parameters.
