Abstract
The modulation of electronic or transition states plays an important role in improving the selectivity and reactivity of chemical reactions. In recent years, the strong coupling between an optical mode and excitons or molecular vibrational modes has received attractive attention as a physical phenomenon for controlling the activation energy of chemical reactions by modulating the electronic state or the vibrational state. In this study, we investigated the spectral properties of hybrid states formed by the strong coupling between plasmon and molecular/intermolecular vibrational modes in the infrared wavelength region. The strong coupling between plasmon and molecular excitonic states have been also studied for demonstrating how to confirm the formation of hybrid states. We developed a highly efficient photochemical reaction field by using modal strong coupling systems between plasmons and different optical modes.
