4-Hydroxyacetophenone monooxygenase is an enzyme that transforms piceol into O-acetylhydroquinone. This enzyme is found in Pseudomonas fluorescens. See also ...
An infrared spectroscopy correlation table (or table of infrared absorption frequencies) is a list of absorption peaks and frequencies, typically reported in wavenumber, for common types of molecular bonds and functional groups.
Acetophenone is formed as a byproduct of the cumene process, the industrial route for the synthesis of phenol and acetone.In the Hock rearrangement of isopropylbenzene hydroperoxide, migration of a methyl group rather than the phenyl group gives acetophenone and methanol as a result of an alternate rearrangement of the intermediate:
4-Hydroxyacetophenone (p-hydroxyacetophenone, piceol) This page was last edited on 27 February 2021, at 08:40 (UTC). Text is available under the Creative Commons ...
The 4 substrates of this enzyme are (4-hydroxyphenyl)ethan-1-one, NADPH, H +, and O 2, whereas its 3 products are hydroquinone acetate ester, NADP +, and H 2 O. This enzyme belongs to the family of oxidoreductases , specifically those acting on paired donors, with O2 as oxidant and incorporation or reduction of oxygen.
Infrared spectroscopy (IR spectroscopy or vibrational spectroscopy) is the measurement of the interaction of infrared radiation with matter by absorption, emission, or reflection. It is used to study and identify chemical substances or functional groups in solid, liquid, or gaseous forms. It can be used to characterize new materials or identify ...

By applying intense tunable IR lasers, like IR-OPOs or IR free electron lasers, the wavelength dependence of the IRMPD yield can be studied. [5] [6] This infrared photodissociation spectroscopy allows for the measurement of vibrational spectra of (unstable) species that can only be prepared in the gas phase. Such species include molecular ions ...
