The area in the readout from 500 to 1500 units is known as the fingerprint region in this technique, and a peak around 1700 wavenumbers is indicative of a carbonyl compound.
One modification of this technique puts the sample over a zinc selenide crystal and uses attenuated total reflection to analyze the sample in the original phase. Anharmonicity, chemical exchange and hydrogen bond formation and breaking can be detected in the two-dimensional version of this technique, which uses a pair of pulses followed by a detection phase. Samples are prepared by grounding into a mull of nujol or smearing onto salt plates. The area in the readout from 500 to 1500 units is known as the fingerprint region in this technique, and a peak around 1700 wavenumbers is indicative of a carbonyl compound. For 10 points, name this type of spectroscopy that uses wavelengths longer than visible light to probe vibrational modes of molecules.
