Surface-aligned photoreaction of DBr with C2H4 on Pt(111)

For ethylene and deuterium bromide coadsorbed on Pt(111) at 52 K, evidence is presented for photon-driven production of ethane and bromoethane. The formation of bromoethane is ascribed to a surface-aligned concerted reaction between photoexcited DBr-, or its vibrationally excited, electronically quenched form, and C2H4. This reaction is more likely when the C2H4 is adsorbed over a chemisorbed layer of DBr. Ethane is best accounted for on the basis of photogenerated energetic D atoms reacting with C2H4 to form C2H4D, and the latter being hydrogenated during temperature-programmed desorption by active D atoms derived from dissociating DBr. When C2H4 and DBr are both in the first layer, the π-bonded form of ethylene reacts more readily than the di-σ-bonded form.

Metastable Decompositions of C5H10O+. Ions with the Oxygen on the Middle Carbon: A Test for Energy Randomization

This study was undertaken to define the mechanisms of metastable decomposition of C5H10O+. ions with the oxygen on the middle carbon, and to test the assumption that internal energy becomes randomly distributed prior to the unimolecular decompositions of gaseous ions.CH3CH2C(=OH+)CH2CH2. (2), CH3CH2C(=OH+).CHCH3 (3), and CH3CH2C(OH+.)HCH=CH2 (4) all rearrange to CH3CH2C(=O+.)CH2CH3 (1) prior to metastable decomposition.However, 2 - 4 lose ethyl 50 - 100 times as often as they lose ethane following rearrangement to 1, while 1 formed by ionization of 3-pentanone loses exclusively ethane.These differences are attributed to excess energy in the isomerized ions. 3-Pentanone ions formed by isomerization of 2 - 4 lose ethyl and ethane from opposite sides at unequal rates, possibly owing to incomplete randomization of energy following isomerization.
