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.

X-ray photoelectron spectroscopy is based on the same principle as all photoelectron spectroscopy methods. If a molecule or material is irradiated with light of a known energy above the ionization ...

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

Near-IR spectroscopy belongs to the group of vibrational spectroscopy techniques, along with mid-infrared spectroscopy (primarily FT-IR) and Raman spectroscopy. The first near-IR spectrometers were ...

X-rays, a type of electromagnetic radiation with wavelengths from 0.01 to 10 nanometers, pack enough energy to pierce materials and interact with inner-shell electrons. 1 When they hit a sample, ...
