FIG. 2.

Simulated buildup curves of magnetization transfer from spin 2 (blue) to spin 1 (red) and spin 3 (green) in model spin systems AGG-2, AGG-3, and GGV-3 with various recoupling sequences. ZQ sequences: RFDR, ${\omega }_r/2\pi =10\text{kHz}$, ${\omega }_1=50\text{kHz}$; $\text{SR}{4}_4^1$, ${\omega }_r/2\pi =30\text{kHz}$, ${\omega }_1=30\text{kHz}$. DQ sequence: $\text{R}{12}_2^5$, ${\omega }_r/2\pi =15\text{kHz}$, ${\omega }_1=90\text{kHz}$. Mixed sequence: DRAWS, ${\omega }_r/2\pi =10\text{kHz}$, ${\omega }_1=85\text{kHz}$.
