Plasmonic nanogap confinement extends sum frequency vibrational spectroscopy to the nanoscale, enabling direct imaging of ...

Dual-comb spectroscopy (DCS) has rapidly become a cornerstone of precision molecular detection, offering unparalleled resolution, broad spectral coverage, and fast acquisition speed. From fundamental ...

Definition: Fourier Transform Infrared (FTIR) Spectroscopy is a highly specialized type of IR spectroscopy. It's the most common way IR measurements are carried out today. FTIR is known for its speed, ...

Coupling mid-infrared “idler” photons with near-infrared “signal” photons enables cheaper, smaller and more efficient machines for uses such as greenhouse gas monitoring to medical diagnostics.

The molecular gas outflow from the quasar includes hydroxyl (OH) (top). Due to the motion of the molecular gas toward the observer, the OH peak in the absorption spectrum (bottom, dashed blue line) ...

Photothermal AFM-IR, commonly referred to as AFM-IR, is an analytical technique used to understand the chemistry of a material at the nanoscale. It combines the nanoscale spatial resolution of atomic ...

Sum-frequency generation (SFG) is a powerful vibrational spectroscopy that can selectively probe molecular structures at surfaces and interfaces, but its spatial resolution has been limited to the ...
