The reaction is initiated by the 193 nm in situ photodissociation of N$_2$O to produce N$_2$ + O($^{1}$D). We assume the O($^{1}$D) photoproduct reacts with the parahydrogen host to create H-atoms. What we observe is growth of cis-HNNO right after photolysis is stopped along with a later delayed growth in trans-HNNO. We assign our peaks by comparison with a previous Xe matrix isolation study\textbf{104}, 3681-3692 (2000).} and recent ab initio calculations\textbf{134}, 084308 (2011).} of the anharmonic vibrational frequencies and isotopic shifts. We performed some experiments using the $^{15}$N$_2 ^{18}$O precursor molecule. Detailed study of the reaction kinetics indicate that at 1.8 K the cis-isomer is formed exclusively by the reaction, but then converts to the lower energy trans-isomer with time. These results are surprising because a 40 kJ/mol barrier is predicted for the H + N$_2$O reaction, yet the reaction readily proceeds even at 1.8 K. We are currently studying this reaction under a variety of conditions and the most current results and analysis will be presented. en_US dc.language.iso en en_US dc.publisher Ohio State University en_US dc.title COLD CHEMICAL REACTIONS OF H-ATOMS AND N$_2$O IN SOLID PARAHYDROGEN AT 2 K en_US dc.type Article en_US
