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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
