Visualizing individual molecules with chemical recognition is a longstanding target in catalysis, molecular nanotechnology and biotechnology. Molecular vibrations provide a valuable ‘fingerprint’ for such identification. Vibrational spectroscopy based on tip-enhanced Raman scattering allows us to access the spectral signals of molecular species very efficiently via the strong localized plasmonic fields produced at the tip apex. However, the best spatial resolution of the tip-enhanced Raman…

Resolving the Correlation between Tip-Enhanced Resonance Raman Scattering and Local Electronic States with 1 nm Resolution
TLDR
This work reports on tip-enhanced resonance Raman spectroscopy (TERRS) of ultrathin ZnO layers epitaxially grown on a Ag(111) surface, and suggests that TERRS is a new approach for the atomic-scale optical characterization of local electronic states at near-atomic resolution.
Visualizing vibrational normal modes of a single molecule with atomically confined light
TLDR
The vibrational normal modes in a single molecule are imaged using tip-enhanced Raman spectromicroscopy performed in the atomistic near-field, and ångström-scale resolution is attained at subatomic separation between the tip atom and a molecule in the quantum tunnelling regime of plasmons.

TLDR
The calculations indicate that the maximum enhancement factor achievable through electromagnetics is of the order 10(11), which can qualitatively explain why only very few surface sites seem to contribute to the measured signal in single-molecule SERS experiments.

TLDR
Density functional theory calculations reveal that the most significant spectral change seen for a gold-4,4′-bipyridine-gold junction results from the deformation of the pyridine ring in contact with the drain electrode at high voltage, and these calculations suggest that a stronger bonding interaction between the molecule and the drain may account for the nonlinear dependence of conductance on bias voltage.
