What is the source of FTIR instrument?

A Fourier-transform infrared (FTIR) spectrometer is the instrument used to perform FTIR spectroscopy. It works by measuring the absorption of infrared radiation by a sample. It consists of an interferometer and a detector to measure the signal.


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.


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?

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 is infrared absorption?

This phenomenon is the absorption of infrared waves in a material.

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.

What are the key differences between Raman and FTIR spectroscopy techniques?

Raman spectroscopy measures the scattering of light, while FTIR spectroscopy measures the absorption of infrared light. Raman spectroscopy is better for analyzing crystalline materials, while FTIR is more suitable for identifying functional groups in organic compounds. Additionally, Raman spectroscopy is less sensitive to water interference compared to FTIR spectroscopy.
