分子振动与光学共振的强耦合是实现光子控制化学反应的一条有前途的途径。由于它们的窄线宽和紧密的能量接近，振动跃迁提供了有趣的机会，使多个物质状态与相同的光学状态强耦合，形成具有显着杂化的极化激元。三种有机金属离子的溶液被用来控制在200 cm-1窗口的分子共振的数量，能量和强度，允许系统的调查形成的三个，四个和五个极化激元。同时耦合到一个光学模式的额外分子的存在并没有显着影响拉比分裂能量的一个给定的分子共振，但基本上改变了所得的极化激元的Hopfield混合系数。因此，共谐振腔的引入是用于修改极化激元的性质的替代手段。
Strong coupling of molecular vibrations to optical resonances is a promising route toward photonic control over chemical reactions. Due to their narrow line widths and close energy proximity, vibrational transitions afford intriguing opportunities for strong coupling of multiple matter states with the same optical state to form polaritons with significant hybridization. Solutions of three organometallic ions were used to control the number, energy, and intensity of molecular resonances in a 200 cm–1 window, allowing for a systematic investigation of the formation of three, four, and five polaritons. The presence of additional molecules simultaneously coupled to an optical mode did not significantly affect the Rabi splitting energy of a given molecular resonance, but did substantially alter the Hopfield mixing coefficients of the resulting polaritons. The introduction of a co-resonator is therefore an alternative means for the modification of the properties of polaritons.
