Infrared Spectroscopy

What is infrared spectroscopy used for

an analytical technique used to identify functional groups within organic molecules.

What is the limitation of this technique

Only identifies functional groups but not the number of it present in the molecule

How does it work

Covalent bonds absorb specific amounts of energy in the form of infrared radiation.

By measuring the wavelength of energy absorbed by the molecule, the types of bonds present can be determined.

What is the fingerprint region

The area on the spectrum below 1500cm–1 which is unique to each molecule, It is not used as it is too complicated to analyse

IR and Global warming
