New Fabry-Perot optical cavities were developed that enable studying Vibrational Strong Coupling (VSC) by Nuclear Magnetic Resonance (NMR) spectroscopy. We demonstrate that the London dispersion-driven conformational equilibrium of a molecular balance is altered when the C−H stretching vibration is strongly coupled to the cavity. Unexpectedly, VSC does not substantially affect molecular electron density
开发了新的法布里-珀罗光学腔,可以通过核磁共振 (NMR) 光谱研究振动强耦合 (VSC)。我们证明,当 C−H 伸缩振动与空腔强烈耦合时,伦敦色散驱动的分子平衡构象平衡会发生改变。出乎意料的是,VSC 并没有显着影响分子电子密度分布,这对极化子化学中可能发挥作用的机制具有深远的影响。
