Photodissociation dynamics of the allyl radical
HJ Deyerl, I Fischer, P Chen - The Journal of chemical physics, 1999 - pubs.aip.org
The photochemistry and photodissociation dynamics of the allyl radical upon ultraviolet (UV)
excitation is investigated in a molecular beam by using time-and frequency-resolved
photoionization of hydrogen atoms with Lyman-α-radiation. The UV states of allyl decay by
internal conversion to the ground state, forming vibrationally hot radicals that lose hydrogen
atoms on a nanosecond time scale. Two channels are identified, formation of allene directly
from allyl, and isomerization from allyl to 2-propenyl, with a subsequent hydrogen loss …
