This work presents a mathematical framework that enables the simulation for the dynamics of the spin-3/2 23Na density operator.
Figure 1: The SBE system matrix, $$$\mathbf{L}$$$, colour-coded to indicate source of terms: Red-shaded entries are associated with RF excitation; Yellow-shaded entries are off-resonance terms; Green-shaded terms are associated with residual quadrupolar oscillation; Blue-shaded terms are associated with the fluctuating quadrupolar interaction.
