A spectrometer that directly detects the vibrational “fingerprint” of molecules offers a sensitive new way of deducing a material’s chemical make-up. The device, which was developed by researchers in ...

FTIR deals with the infrared region of the electromagnetic spectrum, and it works by measuring how much light is absorbed by the bonds of vibrating molecules to provide a molecular fingerprint. The ...

Researchers have demonstrated a compact frequency-comb apparatus that rapidly measures the entire infrared band of light to detect biological, chemical and physical properties of matter. Researchers ...

Fourier transform infrared (FTIR) spectroscopy is the preferred method of infrared spectroscopy. In this approach, IR radiation passes through a sample, where some of it is absorbed by the sample ...

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 ...

Wet comb: NIST’s tabletop frequency comb being used to identify water molecules in air. The yellow squiggle at the top of the screen is the electric field of mid-infrared laser light that has passed ...

Buckyballs’ large size and intricate structure have long captured scientists’ interest, even if practical applications for the 60-carbon molecules remain elusive. Now, more than 30 years after their ...

Researchers at the US National Institute of Standards and Technology (NIST) and collaborators have demonstrated a compact frequency-comb apparatus that rapidly measures the entire infrared band of ...

Modern technology uses many frequencies of electromagnetic radiation for communication, including radio waves, TV signals, microwaves and visible light. Now, a University of Utah study shows how ...

In a new study published in Science, researchers have developed a new method for detecting infrared light by changing its frequency to a corresponding frequency in the range of visible light.
