Water vapour continuum absorption refers to the smooth, broadband absorption observed in the atmospheric windows, which fills the spectral gaps between distinct molecular absorption lines. This ...

If you were to use infrared (IR) transmission microscopy, you would appreciate its chemical quantification abilities—unless your object of study was a hydrated cell. In that case, you might complain ...

What is Surface-Enhanced Infrared Absorption (SEIRA) Spectroscopy? Surface-enhanced infrared absorption (SEIRA) spectroscopy is an advanced analytical technique that combines the principles of ...

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.

Imaging live cells without disrupting their natural behavior or damaging their structures is one key challenge in biomedical optics, and has been tackled in multiple ways. A project at NIST has now ...

Researchers have developed a low-cost method for the analysis of interfacial molecules by combining ATR-IR with precise gap-control and multi-variate data analysis. A novel spectroscopic method ...

Photothermal AFM-IR, or AFM-IR, is an analytical method used for chemical identification in a materials sample at the nanoscale. AFM-IR incorporates both the nanoscale spatial resolution of atomic ...
