Abstract
HOCO is a vital intermediate in the combustion reaction $OH + CO \leftrightarrow H + CO_{2}$ but is hard to study experimentally due to its limited lifetime. C.B. Moore and coworkers (JPC, 97, 11194) recently generated HOCO by the ultraviolet dissociation of acrylic acid $(C_{2}H_{3}CO_{2}H)$, but little is known about this reaction pathway. This work investigates the dynamics of $C_{2}H_{3}CO_{2}$H photodissociation upon excitation at 193 nm by use of a crossed laser-molecular beam apparatus. Specifically, reaction pathways, quantum yields, and energy released to translation are presented. Unimolecular decomposition of $HOCO to H + CO_{2}$ is also discussed.
