The Fundamentals of Infrared Spectroscopy
www.midac.comThe infrared spectrum is measured by either absorbance or percent transmittance on the y-axis and by either the wavelength (um) or wavenumber (cm-1) to measure the position of an infrared absorptionon the x -axis. Most compounds have characteristic absorptions in the infrared region.

Recent work, using attenuated total reflectance (ATR) infrared spectroscopy, shows isobestic points for both ordinary and heavy liquid water, with respect to temperature. For H2O these are at around 600, 1600, 1680, & 3550 cm-1 [1738], in agreement with earlier work [530 ,699].g Shown

The infrared region can be divided into two categories based on their radiation properties. Reflected IR (.7 µm - 3.0 µm) is used for remote sensing. Thermal IR (3 µm - 35 µm) is the radiation

The Electromagnetic Spectrum Radiation is one way to transfer heat. To “radiate” means to send out or spread from a central location.

spie.org1.2 Classification of Infrared Detectors Optical radiation is considered to be radiation ranging from vacuum ultraviolet to submillimeter wavelengths (25 nm to 3000 mm). The terahertz (THz) region of electromagnetic spectrum (see Fig. 1.2) is often described as the final unexplored area of the spectrum and still presents a challenge for both elec-

For example, an infrared search reveals huge clouds of formaldehyde in space, each more than a million times more mas-sive than the Sun. Some ultraviolet light comes from powerful galaxies very far away. Astronomers

In reality, gases absorb IR light selectively, and most of the gas in the atmosphere doesn’t interact with IR ...
