Dipole moment
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.
(Latteman, M, 2003) attributed a Si-C stretch at 782-794cm-1
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
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.
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.

Potassium fluoride isn't used in infrared spectroscopy.

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.
its mr will change from 98.15 to 100.158
Sodium chloride was used as crystal in infrared spectroscopy; but his hygroscopicity is a major disadvantage.
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.
Freqency in electromagnetic waves is the number of waves that pass one point in a second.
