Infrared spectroscopy is capable of providing a complex fingerprint region which is unique to the compound being examined. This allows the compound to be identified by matching its sample spectrum to the standard. Computer control of instruments also allows this to be readily carried out.

What are the weaknesses of infrared spectroscopy?
Infrared spectroscopy cannot be used quantitatively. The sample preparation is also complex. It may be robust as the sample preparation may affect its results.
Infrared spectroscopy analysis of unknown compounds?
Infrared spectroscopy is a powerful technique used to identify functional groups in unknown compounds by measuring the absorption of infrared light. By comparing the peaks in the infrared spectrum of an unknown compound to reference spectra, the functional groups present can be identified. This information can help in determining the molecular structure and composition of the compound.
Is potassium fluoride IR active?
Potassium fluoride isn't used in infrared spectroscopy.
How does infrared spectroscopy identify organic compounds?
Infrared spectroscopy identifies organic compounds by measuring the absorption of infrared radiation by the compound's functional groups. Each functional group absorbs infrared radiation at specific frequencies, which produce characteristic peaks in the IR spectrum. By comparing these peaks to reference spectra, the functional groups present in the compound can be identified.
What is the difference ultraviolet and infrared spectroscopy?
Ultraviolet (UV) spectroscopy involves measuring absorption of light in the UV region, typically ranging from 200 to 400 nm. Infrared (IR) spectroscopy, on the other hand, involves measuring absorption of infrared radiation, typically in the range of 4000 to 400 cm-1. Both techniques provide information about molecular structure and functional groups present in a compound, but they probe different regions of the electromagnetic spectrum.
