Spectroscopy seems simple: split a beam of light into its constituent wavelengths with a prism or diffraction grating, and measure the intensity of each wavelength. The devil is in the details, though ...

Researchers have developed a compact infrared spectrometer. It's small enough to fit on a computer chip but can still open up interesting possibilities -- in space and in everyday life. Nowadays, a ...

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 ...

Definition: Fourier Transform Infrared (FTIR) Spectroscopy is a highly specialized type of IR spectroscopy. It's the most common way IR measurements are carried out today. FTIR is known for its speed, ...

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 ...
