The fingerprint region in infrared spectrscopy is used for identifying compounds by matching the sample spectrum to the standard. The fingerprint region is specific to each compound. Very similar compounds will have small differences in the fingerprint region so the fingerprint region can be used to differentiate them.

What are the strengths of infrared spectroscopy?

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 other regions of spectroscopy aside from the visible region?

Other regions of spectroscopy include ultraviolet (UV), infrared (IR), microwave, radio, X-ray, and gamma-ray spectroscopy. Each region provides information about different aspects of a molecule's structure and behavior. UV spectroscopy is commonly used to study electronic transitions, while IR spectroscopy is utilized for molecular vibrations.


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


Can be visible or infrared?

I can't think of anything that could be those two and nothing but those two. Electronic structure spectroscopy is generally in the UV/Visible band, but I suppose it could extend down into the near IR. Vibrational spectroscopy (with rotational fine structure) is in the IR, but doesn't make it up into the visible region.


What is the traditional method of infrared spectroscopy?

Infrared spectroscopy (IR spectroscopy) is the subset of spectroscopy that deals with the infrared region of the electromagnetic spectrum. It covers a range of techniques, with the most common type by far being a form of absorption spectroscopy. As with all spectroscopic techniques, it can be used to identify a compound and to investigate the composition of a sample. For further details, see the links to the left of this answer.

What is the fingerprint region in infrared spectroscopy?

The fingerprint region in infrared spectroscopy refers to the region of the spectrum typically between 1500-500 cm-1 where complex vibrational modes of a molecule are observed. This region is unique to each compound and provides a unique "fingerprint" that can be used to identify and characterize a compound.


Why is C-H bending often not very distinctive in drug molecules in infrared spectroscopy?

This is because the fingerprint region is often very complex.

Finger print region in IR spectroscopy?

The fingerprint region in IR spectroscopy typically ranges from 1500-500 cm-1. This region contains a high density of peaks that are unique to the molecule being analyzed, offering a unique fingerprint for identification. It is particularly useful for identifying functional groups and providing fine structural details of a compound.

What is the significance of Finger print region in Infra red spectroscopy?

Compare the infra-red spectra of propan-1-ol and propan-2-ol. Both compounds contain exactly the same bonds. Both compounds have very similar troughs in the area around 3000 cm-1 - but compare them in the fingerprint region between 1500 and 500 cm-1. The pattern in the fingerprint region is completely different and could therefore be used to identify the compound. So . . . to positively identify an unknown compound, use its infra-red spectrum to identify what sort of compound it is by looking for specific bond absorptions. That might tell you, for example, that you had an alcohol because it contained an -OH group. You would then compare the fingerprint region of its infra-red spectrum with known spectra measured under exactly the same conditions to find out which alcohol (or whatever) you had.

What is range for FTIR?

FTIR or Fourier transform Infared spectroscopy is the simultaneous collection of spectral data in the wide spectral range.Which has quite an advantage over a dispersive spectrometer which only covers a narrow range of wave lengths at once.
