A variant of this technique eliminates lots of preparation by passing light through a zinc selenide crystal such that it experiences total internal reflection with the sample. Ultrafast lasers facilitate the two-dimensional Fourier transform variant of this technique. NASA has a new database of data from this technique for polycyclic aromatic hydrocarbons. Solid samples can be prepared for it by being integrated with potassium bromide or ground into a (*) mull. Molecules containing carbonhydrogen and triple bonds produce high stretching frequencies in this technique, and carbonyls produce a characteristic strong peak at 1700 inverse centimeters. The range on its readout from 1450 and 600 inverse centimeters is called the fingerprint region. For 10 points, name this type of spectroscopy that uses light with a long
