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. |
