Abstract
When $10^{\circ}\,K$ argon matrices containing small amounts of $H_{2}S + O_{3}, H_{2}S + NO_{2}$ or $OCS + O_{3}$ are irradiated with the full light of a mercury are and subsequently allowed to anneal, several visible banded chemiluminescent emission systems are observed. An analysis of these emissions via optical multichannel techniques had revealed two new systems of the SO molecule in addition to those emissions of $SO_{2}$ and, in some cases, $O_{2}$ and $S_{2}$. The more intense system consisted of as many as 10 members and is located between $\sim 490$ and 870 nm. A second, much weaker, system is situated between $\sim 385$ and 600 nm. The electronic origins of each system were determined from the results of oxygen-18 isotopic experiments while selective laser photolysis studies provided additional information concerning the various reaction mechanisms involved. Experimental details, as well as the implications of the results, will be briefly discussed.
