he infrared multiphoton decomposition (IR MPD) of tert-butyl-d, bromide as a function of pressure and fluence is reported.The major decomposition route was molecular elimination of DBr in accord with earlier pyrolysis studies. Evidence for asecond channel comprising Br and tert-butyl radicals was found at high fluence or high pressure. The pressure dependenceof this second channel suggests that through energy pooling collisions the molecules can reach an otherwise inaccessible channel.The effect of added gases (02N,2 ,H e, Ar, DBr, and 2-methylpropene-d8)o n the MPD is presented. This study is a furtherindication of the utility of a new method of analysis of MPD experiments.
