Short summary
Parallel NMR (nuclear magnetic resonance) detection enhances measurement throughput for high-throughput screening. However, local gradients in parallel detectors cause field spillover in adjacent channels, leading to spin dephasing and signal loss. This study introduces a compensation scheme using optimized pulses to mitigate gradient-induced field inhomogeneity through coherence locking. The proposed approach offers an effective solution for NMR probes with parallel, independently switchable gradient coils.
