Determination of absolute photoionization cross sections for isomers of C3H5: allyl and 2-propenyl radicals
نویسندگان
چکیده
The photoionization (PI) cross sections of allyl and 2-propenyl radicals to form C3H þ 5 were measured using tunable vacuum ultraviolet (VUV) synchrotron radiation coupled with photofragment translational spectroscopy. At 10 eV, the cross sections were found to be 6.2 1.2 and 5.1 1.0 Mb, respectively. Using these values, the PI efficiency curves for each radical were placed on an absolute scale from 7.75 to 10.75 eV. 2003 Elsevier B.V. All rights reserved.

Determining the partial photoionization cross-sections of ethyl radicals.
Using a crossed laser-molecular beam scattering apparatus, these experiments photodissociate ethyl chloride at 193 nm and detect the Cl and ethyl products, resolved by their center-of-mass recoil velocities, with vacuum ultraviolet photoionization. The data determine the relative partial cross-sections for the photoionization of ethyl radicals to form C2H5+, C2H4+, and C2H3+ at 12.1 and 13.8 eV...
متن کاملCompeting isomeric product channels in the 193 nm photodissociation of 2-chloropropene and in the unimolecular dissociation of the 2-propenyl radical
This paper presents product translational energy spectroscopy measurements of the primary photofragmentation channels of 2-chloropropene excited at 193 nm and of the unimolecular dissociation of the 2-propenyl radical. Tunable vacuum ultraviolet ~VUV! photoionization of the products allows us to distinguish between the various product isomers formed in these processes. The data show evidence fo...
متن کاملGas Phase Kinetics and Equilibrium of Allyl Radical Reactions with NO and NO<sub>2</sub>
Allyl radical reactions with NO and NO2 were studied in direct, time-resolved experiments in a temperature controlled tubular flow reactor connected to a laser photolysis/photoionization mass spectrometer (LP-PIMS). In the C3H5 + NO reaction 1, a dependence on the bath gas density was observed in the determined rate coefficients and pressure falloff parametrizations were performed. The obtained...

ion from 1-hexene, changes in reactions involving 1-hexene also affect the prediction of 1,3-butadiene. For example, the predicted peak concentration of 1,3-butadiene increases by 13% of the MPC due to a higher concentration profile of 1-hexene after a slower 1-hexene thermal decomposition reaction (using the generic rate of reaction 1 in Table 1) is selected. 1-Butylene has an important effect...
متن کاملDetermination of absolute photoionization cross sections of the phenyl radical.
Photoionization cross sections of the phenyl radical to form the phenyl cation were measured using tunable vacuum ultraviolet synchrotron radiation coupled with photofragment translational spectroscopy. The phenyl radical was produced via 193- or 248-nm dissociation of chlorobenzene. At 10.0 eV, the photoionization cross sections for the phenyl radical averaged over product channels were found ...
