Modeling the Effect of Small Gaps in Surface-Enhanced Raman Spectroscopy

The electromagnetic mechanism of surface-enhanced Raman spectroscopy (SERS) involves plasmon enhancement of the optical-frequency electric fields on the surfaces of silver or gold (or sometimes other) nanoparticles where molecules that exhibit Raman scattering are located. It has long been recognize...
