Due to spectator secondary electrostatic interactions, nonsymmetric mono-Boc-mono-acetyl terminated hydrazide-based oligomers displayed a head-to-tail dimerization mode, which was evidenced by 1H NMR, and 2D NOESY experiments. Dynamic behavior of the molecular duplex strands was also explored by variable temperature 1H NMR experiments.

肼基低聚物显示出头对尾二聚模式,这一点在 1H NMR 和二维 NOESY 实验中得到了证明。变温 1H NMR 实验还探索了分子双链的动态行为。
