IR spectroscopy is useful in identifying functional groups in your sample. Many functional groups have specific absorption frequencies, so examination of IR spectra can tell you which functional groups are present (but not where they are structurally in your molecule). A table of common IR absorption frequencies are here: http://www.chem.ucla.edu/~webspectra/irtable.html Most of the time IR is used with NMR to identify a compound. IR can often be used independently to see if a reaction has worked (like if you are adding an azido group to your compound, you can use IR to see if your purified product has an azido absorption).
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.
Absorption peaks of infrared waves is specific for each chemical entity.
The principle of fluorescence spectroscopy is the interaction with light image.
Potassium fluoride isn't used in 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.

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.

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.
