A fingerprint region is a "specific" region that a molecule shows peak. They are different for all vibrations so that a fingerprint is different for all people.

What are selection rules for IR spectroscopy?
Dipole moment
Applications of IR?
The application for IR spectroscopy include the identification of functional group and structure elucidation. It also includes the identification of substances and detection of impurities.
Where is IR peak of Silicon Carbide using FT IR spectroscopy?
(Latteman, M, 2003) attributed a Si-C stretch at 782-794cm-1
Why water cannot be used as solvent in IR spectroscopy?
water is ir active so produces a peak due to it OH group at 3500cm-1 this is why equipment should be keep in oven
Which solvents are used in IR spectroscopy?
Cyclohexane is used as a solvent for xylene FTIR. Some other solvents used are hexane, diethyl ether, acetone etc. depending on the type of analyte.
What are selection rules for IR spectroscopy?
Dipole moment
What has the author S Wartewig written?
S. Wartewig has written: 'IR and Raman spectroscopy' -- subject(s): Infrared spectroscopy, Raman spectroscopy
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.
Use of kbr in ir spectroscopy?
KBr is used mostly in IR Spectroscopy techniques because it do not absorbs moisture at room temperature as compared to NaCl. More over it do not give its own peak.
Which is the best preparation for IR spectroscopy solid liquid or gas?
liquid
Why are salt crystal cells used in IR spectroscopy instead of glass or quartz cells?
Glass and quartz cells have high absorbency's of photons in the IR range, these are better for analyses in the UV/Vis region. Salt crystal cells, however, typically absorb very little IR radiation, making them optimal for IR spec.
What Solvents can damage KBr cell windows in IR-spectroscopy?
Easy - water.
Is potassium fluoride IR active?
Potassium fluoride isn't used in infrared spectroscopy.
Applications of IR?
The application for IR spectroscopy include the identification of functional group and structure elucidation. It also includes the identification of substances and detection of impurities.
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.

How does IR spectroscopy works?
IR spectroscopy works by using infrared beams to work out the structure of a chemical. The chemical is placed in an inert substance, e.g. Potassium Bromide. The refraction of the beams brings up a characteristic trace of the mystery compound, which can then be used to work out the structure.
