Absorption spectroscopy Wikipedia

Absorption spectroscopy refers to spectroscopic techniques that measure the absorption of radiation, as a function of frequency or wavelength, due to its interaction with a sample absorbs energy, , photons, from the radiating field. The intensity of the absorption varies as a function of frequency, and this variation is the absorption spectrum.

1/12/2012· Infrared (IR) spectroscopy in the to 20 μm (500–4000 cm −1) range (midIR) is a direct probe of the molecular vibrations in a absorption spectra of organic compounds are often used to specifically identify chemical species. By combining microscopy and spectroscopy, chemical analysis can be done on a micrometer scale.


Nondispersive infrared sensor Wikipedia

A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas is nondispersive in the fact that no dispersive element ( a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing.
