Freqency in electromagnetic waves is the number of waves that pass one point in a second.
Potassium fluoride isn't used in infrared spectroscopy.
its mr will change from 98.15 to 100.158
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.
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.
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.

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.

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.
Sodium chloride was used as crystal in infrared spectroscopy; but his hygroscopicity is a major disadvantage.

Raman Spectroscopy is a spectroscopic technique in condensed matter physics and chemistry. It studies vibrational, rotational & low-frequency modes in systems.
