Surface plasmons can provide a novel route to induce and simultaneously monitor selective bond formation and breakage. Here pH-induced protonation, followed by plasmon-induced deprotonation of 2-mercaptopyridine was investigated using surface- and tip-enhanced Raman scattering (SERS and TERS). A large difference in the deprotonation rate between SERS and TERS will be demonstrated and discussed with respect to hot-spot distribution.
表面等离子体激元可以提供一条诱导并同时监测选择性键形成和断裂的新途径。在此，利用表面增强拉曼散射（SERS）和针尖增强拉曼散射（TERS）研究了pH诱导的质子化，随后2-巯基吡啶的等离子体诱导去质子化过程。将展示SERS和TERS去质子化速率的巨大差异，并结合热点分布进行讨论。
