INFRARED SPECTROSCOPY

_____________________________

Infrared spectroscopy (IR spectroscopy) is the spectroscopy that deals with the infrared region of the electromagnetic spectrum, that is light with a longer wavelength and lower frequency than visible light. It covers a range of techniques, mostly based on absorption spectroscopy.

SOURCES

______________________________

Instruments for measuring infrared absorption all require a source of continuous infrared radiation and a sensitive infrared transducer, or detector. Infrared sources consist of an inert solid that is electrically heated to a temperature between 1,500 and 2,200 K. The heated material will then emit infra red radiation.
