This is most pronounced in direct sunlight conditions where the sun has a very high energy distribution in the infrared region.

In the infrared region of the spectrum it acts as a metal-like mirror.

It will survey the sky in the infrared region.

Absorption due to these vibrations occurs in the infrared region of the spectrum.

It has an intense pure rotation spectrum in the far infrared region, below about 200 cm.

It produced a coherent light beam in the infrared region of the spectrum at 1.15 micrometres.

As a result, it is possible to use excitation in the far infrared region where the human body shows good transparency.

Molecules absorb light from the infrared region of the spectrum differently and produce characteristic patterns.

The is calculated in the wavelength interval of 2.2-20 (near- and mid- infrared region).

Rather it is in the infrared region which we can "feel" as warm, but cannot see visually.
