Doner, Anna C.; Webb, Annabelle R.; Dewey, Nicholas S.; Hartness, Samuel W.; Christianson, Matthew G.; Koritzke, Alanna L.; Larsson, Alexander; Frandsen, Kelsey M.; Rotavera, Brandon published the artcile< Vacuum-ultraviolet absorption cross-sections of functionalized four-carbon species>, Related Products of 627-27-0, the main research area is four carbon species vacuum UV differential absorption spectroscopy.
Absorption cross-sections were measured in the vacuum UV from 5.17 – 9.92 eV using differential absorption spectroscopy for 33 four-carbon species: n-butane, trans-2-butene, cis-2-butene, butanal, butyric acid, ethyloxirane, trans-2,3-dimethyloxirane, cis-2,3-dimethyloxirane, 2-methyloxetane, 2,2′-bioxirane, vinyl oxirane, 3,4-epoxybutan-2-one, diacetyl, di-Et ether, Et vinyl ether, vinyl acetate, acetic anhydride, 1-butanol, 3-buten-1-ol, 1-hydroxy-butan-2-one, 1-hydroxy-butan-3-one, 2,3-epoxybutan-1-ol, 3,4-epoxybutan-1-ol, 2-oxetanemethanol, butanone, Me vinyl ketone, 4H-1,3-dioxine, allyl formate, 2-oxobutanal, 4-hydroxybutanal, 2-methyloxetan-3-one, cis-but-2-en-1-ol, and trans-2-but-enal. Uncertainties were quantified in all cases by accounting for errors in gas-phase concentration, exptl. repeatability, and signal-to-noise ratio as a function of photon energy. With the exception of 2-oxobutanal, which is reported with an uncertainty of 10%, convolving the sources of error using the root-sum-square method led to an upper limit of 5% uncertainty above the detection limit, which is largely attributable to chem. purity. The primary objective of the present work is to provide absolute cross-sections along with quantified uncertainty limits. The majority of the absorption spectra, which reflect electronic transitions such as σ → σ* and n → σ*, are reported for the first time and provide insight into fundamental chem. physics, such as vibrational band structure and Rydberg transitions. The quant. spectra in the present work facilitates the discovery of chem. intermediates that support improvement in the accuracy of computational models for low-temperature combustion and atm. chem.
