<abstract>
<p>Rate coefficients, &lt;i&gt;k&lt;/i&gt;, for the gas-phase reaction of CH&lt;sub&gt;3&lt;/sub&gt;COCHO
(methylglyoxal) with the OH and NO&lt;sub&gt;3&lt;/sub&gt; radicals and (CHO)&lt;sub&gt;2&lt;/sub&gt; (glyoxal)
with the NO&lt;sub&gt;3&lt;/sub&gt; radical are reported. Rate coefficients for the OH + CH&lt;sub&gt;3&lt;/sub&gt;COCHO (&lt;i&gt;k&lt;/i&gt;&lt;sub&gt;1&lt;/sub&gt;) reaction were measured under pseudo-first-order
conditions in OH as a function of temperature (211–373 K) and pressure
(100–220 Torr, He and N&lt;sub&gt;2&lt;/sub&gt; bath gases) using pulsed laser photolysis
to produce OH radicals and laser induced fluorescence to measure its
temporal profile. &lt;i&gt;k&lt;/i&gt;&lt;sub&gt;1&lt;/sub&gt; was found to be independent of the bath gas
pressure with &lt;i&gt;k&lt;/i&gt;&lt;sub&gt;1&lt;/sub&gt;(295 K) = (1.29 &amp;plusmn; 0.13) &amp;times;
 10&lt;sup&gt;&amp;minus;11&lt;/sup&gt; cm&lt;sup&gt;3&lt;/sup&gt; molecule&lt;sup&gt;&amp;minus;1&lt;/sup&gt; s&lt;sup&gt;&amp;minus;1&lt;/sup&gt; and a temperature dependence that is
well represented by the Arrhenius expression &lt;i&gt;k&lt;/i&gt;&lt;sub&gt;1&lt;/sub&gt;(&lt;i&gt;T&lt;/i&gt;) = (1.74 &amp;plusmn; 0.20) &amp;times; 10&lt;sup&gt;&amp;minus;12&lt;/sup&gt;
exp[(590 &amp;plusmn; 40)/&lt;i&gt;T&lt;/i&gt;] cm&lt;sup&gt;3&lt;/sup&gt; molecule&lt;sup&gt;&amp;minus;1&lt;/sup&gt; s&lt;sup&gt;&amp;minus;1&lt;/sup&gt; where the uncertainties are 2&amp;sigma; and
include estimated systematic errors. Rate coefficients for the NO&lt;sub&gt;3&lt;/sub&gt; +
(CHO)&lt;sub&gt;2&lt;/sub&gt; (&lt;i&gt;k&lt;/i&gt;&lt;sub&gt;3&lt;/sub&gt;) and NO&lt;sub&gt;3&lt;/sub&gt; + CH&lt;sub&gt;3&lt;/sub&gt;COCHO (&lt;i&gt;k&lt;/i&gt;&lt;sub&gt;4&lt;/sub&gt;) reactions were
measured using a relative rate technique to be &lt;i&gt;k&lt;/i&gt;&lt;sub&gt;3&lt;/sub&gt;(296 K) = (4.0 &amp;plusmn; 1.0) &amp;times; 10&lt;sup&gt;&amp;minus;16&lt;/sup&gt; cm&lt;sup&gt;3&lt;/sup&gt; molecule&lt;sup&gt;&amp;minus;1&lt;/sup&gt; s&lt;sup&gt;&amp;minus;1&lt;/sup&gt; and
&lt;i&gt;k&lt;/i&gt;&lt;sub&gt;4&lt;/sub&gt;(296 K) = (5.1 &amp;plusmn; 2.1) &amp;times; 10&lt;sup&gt;&amp;minus;16&lt;/sup&gt; cm&lt;sup&gt;3&lt;/sup&gt; molecule&lt;sup&gt;&amp;minus;1&lt;/sup&gt; s&lt;sup&gt;&amp;minus;1&lt;/sup&gt;.
&lt;i&gt;k&lt;/i&gt;&lt;sub&gt;3&lt;/sub&gt;(&lt;i&gt;T&lt;/i&gt;) was also measured using an
absolute rate coefficient method under pseudo-first-order conditions at 296
and 353 K to be (4.2 &amp;plusmn; 0.8) &amp;times; 10&lt;sup&gt;&amp;minus;16&lt;/sup&gt; and (7.9 &amp;plusmn; 3.6) &amp;times; 10&lt;sup&gt;&amp;minus;16&lt;/sup&gt; cm&lt;sup&gt;3&lt;/sup&gt; molecule&lt;sup&gt;&amp;minus;1&lt;/sup&gt; s&lt;sup&gt;&amp;minus;1&lt;/sup&gt;,
respectively, in agreement with the relative rate result obtained at room
temperature. The atmospheric implications of the OH and NO&lt;sub&gt;3&lt;/sub&gt; reaction
rate coefficients measured in this work are discussed.</p>
