We demonstrate strong coupling between surface plasmon resonances and molecular vibrational resonances of poly­(methyl methacrylate) (PMMA) molecules in the mid-infrared range through the use of grating coupling, complimenting earlier work using microcavities and localized plasmon resonances. We cho...
