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
Infrared spectroscopy cannot be used quantitatively. The sample preparation is also complex. It may be robust as the sample preparation may affect its results.
Ultraviolet Electromagnetic Radiation
Ultraviolet and the infrared.

Potassium fluoride isn't used in infrared spectroscopy.
Yes. All light is a form of electromagnetic radiation, so this answer applies to all light spectroscopy.
The difference is their wavelengths.

Infrared spectroscopy applications include pharmaceutical, food quality control, elite sports training, and neonatal research. More information can be found on infrared spectroscopy on its wikipedia page.
Ultraviolet
Both infrared and ultraviolet are kinds of electromagnetic radiation, as is the visible light.
Ultraviolet is higher frequency, then visible light, then infrared.
Right between infrared and ultraviolet. It has higher frequencies than infrared; lower frequencies than ultraviolet.
