Vibrational encounters—phonon polaritons meet molecules

Researchers from CIC nanoGUNE BRTA (San Sebastian, Spain), in collaboration with the Donostia International Physics Center (San Sebastián, Spain) and the University of Oviedo (Spain) employed a spectroscopic nanoimaging technique to study how infrared nanolight—in the form of phonon polaritons—and molecular vibrations interact with each other.
