Two-dimensional infrared spectroscopy (2D IR) is a nonlinear infrared spectroscopy technique that has the ability to correlate vibrational modes in condensed-phase systems. This technique provides information beyond linear infrared spectra, by spreading the vibrational information along multiple axes, yielding a frequency correlation spectrum.

Furfuryl alcohol is an organic compound containing a furan substituted with a hydroxymethyl group. It is a colorless liquid, but aged samples appear amber. It is a colorless liquid, but aged samples appear amber.
Furfural is used to make other furan derivatives, such as furoic acid, via oxidation, [30] and furan itself via palladium catalyzed vapor phase decarbonylation. [ 4 ] There is a good market for value added chemicals that can be obtained from furfural.
2,5-Dihydrofuran is an organic compound classified as a monounsaturated derivative of furan. It is a colorless, volatile liquid. It is a colorless, volatile liquid. It can be produced from the acid-catalyzed rearrangement 1‑butene 3,4‑epoxide .
2,5-Dimethylfuran has also been proposed as an internal standard for NMR spectroscopy. 2,5-Dimethylfuran has singlets in its 1 H NMR spectrum at δ 2.2 and 5.8; the singlets give reliable integrations, while the positions of the peaks do not interfere with many analytes. The compound also has an appropriate boiling point of 92 °C which ...
