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.
Is potassium fluoride IR active?
Potassium fluoride isn't used in infrared spectroscopy.
What is the difference ultraviolet and infrared spectroscopy?
FTIR spectroscopy cannot be used to detect all the vibration modes in a molecule. It can be used only to study the non-symmetrical vibrational state in an atom. Using Raman Spectroscopy one can study the symmetric stretch of the atom. For example the symmetric stretch of CO2 which cannot be studied by FTIR can be studied by Raman Spectroscopy. Here the permanent dipole moment of the molecule during a vibrational cycle does not change as it does not involve polarization. As a result, this mode cannot absorb infrared radiation. In many instances, vibrational modes that are not observed by infrared absorption can be studied by Raman spectroscopy as it is the result of inelastic collisions between photons and molecules
What does infrared radiation tell us about molecules?
Infrared radiation can provide information about the types of bonds present in a molecule by measuring the vibrations of the atoms. This helps in identifying functional groups and determining molecular structure. Additionally, infrared spectroscopy can be used to identify unknown compounds and monitor chemical reactions.
Why use KBr in FTIR?
The crystal has no visible peaks in the infrared spectrum making it transparent in ftir.
What has the author Peter R Griffiths written?
Peter R. Griffiths has written: 'Fourier transform infrared spectrometry' -- subject(s): Fourier transform infrared spectroscopy 'Chemical infrared Fourier transform spectroscopy' -- subject(s): Fourier transform spectroscopy, Infrared spectroscopy
Do ultraviolet spectroscopy and infrared spectroscopy involve electromagnetic radiation in their operation?
Yes, both ultraviolet spectroscopy and infrared spectroscopy involve the use of electromagnetic radiation. Ultraviolet spectroscopy uses UV light, which has shorter wavelengths and higher energies, while infrared spectroscopy uses infrared radiation, which has longer wavelengths and lower energies.
Where can one find information about infrared spectroscopy?
Infrared spectroscopy applications include pharmaceutical, food quality control, elite sports training, and neonatal research. More information can be found on infrared spectroscopy on its wikipedia page.
