Abstract A knowledge of the time rates for intermediate reactions
during the photolysis of nitrogen dioxide enables one to deduce the
possible intermediate reactions which are responsible. An experiment has been devised and constructed which will measure the time
rates for photochemical reactions occurring in ranges of one micro
second to several milliseconds after initiation of a short duration
high intensity photolyzing flash.
The method proposed utilizes the examination of the decrease of nitrogen dioxide as a means for observing the photolysis
of nitrogen dioxide. The experimental apparatus consisting of a
source of light for the photolysis of nitrogen dioxide, a flash tube
capable of 200 joules of energy per flash, and a detector of the variation of nitrogen dioxide concentration are described.
Preliminary results demonstrate that the intermediate
mechanism mainly responsible has a reaction time rate associated with it which is much smaller and influences a greater percentage
of the nitrogen dioxide molecules than what would be expected with a
dissociative process. It is suggested that this greater influence and
smaller time rate can be best explained by a collisional energy
transfer process.
