Preparation of certain polymers for this technique typically involves dissolving in a non-hygroscopic solvent before applying the sample to a cell. Preparing solids may involve pushing the sample through a die press to generate a translucent material for this technique or combining the sample with a mulling agent such as Nujol prior to application on potassium bromide salt plates. This technique produces a spectrum with a fingerprint region and characteristic absorbance leads to stretching and bending of bonds in molecules in this technique. It produces a broad peak for alcohols around 3300 inverse centimeters. For 10 points, name this spectroscopic technique using wavelength slightly longer than that of visible light.
