Chemiluminescent Reactions of Group VI Atoms (O(3P) and Se(3P)) with AzideRadicals

摘要

Much recent work has been done on the chemiluminescent reactions of atomicspecies (R) with azide radicals. These reactions typically produce excited-state nitrides or nitrenes which subsequently emit in the UV and visible regions. The high product specificity and large quantum yields observed in many of these reactions has been attributed to electron spin and/or orbital angular momentum constraints. Spin constraints have been found to be important in reactions of the group VII (Halogens) atoms, and orbital constraints have been found to play a role in group V atom reactions. Reactions of group VI atoms with N3 have received less attention even though they are also of interest as chemiluminescent reactions capable of producing specific electronics states of group Vi nitrides.
