Virtually every scientific field has made strides by harnessing light to study the properties of substances. This technique, called spectroscopy, has countless research applications, and innovations ...

A gap-controlled infrared technique makes it possible to study molecular interfaces with high sensitivity using affordable, widely available lab equipment. These molecular interfaces are everywhere—on ...

Optical photothermal infrared (O-PTIR) spectroscopy is an infrared super-resolution measurement technique where a shorter ...

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 ...

Elemental spectroscopy is a method employed to examine in-service fluid samples such as engine oil or hydraulic fluid, to determine the presence and quantity of different substances. This approach ...

Researchers have shown how spectroscopic measurements can be made much faster. By correlating polarization to the color of a pulsed laser, the team can track changes in the spectrum of the light by ...

Near-infrared spectroscopy, known as NIR spectroscopy or NIRS, is a long-established analytical technique. For over 30 years, it has proven to be a fast and reliable method for measuring chemical and ...

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.

While many people often use spectroscopy and spectrometry interchangeably, there are some subtle differences in their exact meanings and the associated experimental techniques they are used to ...
