abstract = {The role of water vapor (H2O) and its hydrogen-bonded
complexes in the gas-phase reactivity of organic compounds
with hydroxyl (OH) radicals has been the subject of many
recent studies. Contradictory effects have been reported at
temperatures between 200 and 400 K. For the OH +
acetaldehyde reaction, a slight catalytic effect of H2O was
previously reported at temperatures between 60 and 118 K. In
this work, we used Laval nozzle expansions to reinvestigate
the impact of H2O on the OH-reactivity with acetaldehyde
between 21.7 and 135.0 K. The results of this comprehensive
study demonstrate that water, instead, slows down the
reaction by factors of ∼3 (21.7 K) and ∼2 (36.2–89.5
K), and almost no effect of added H2O was observed at 135.0
K},
