Candidate interstellar molecules formed from ion-molecule reactions of NO
Molecular orbital calculations using the MINDO/3 method were performed on a series of small molecules to explore reactions of NO which could lead to formation of interstellar molecules. Specifically, equilibrium geometries, isomeric energies, heats of reactions, and reaction pathways were calculated for plausible ion-molecule reactions involving NO and NO/sup +/. The results of these calculations suggest that HNO/sup +/ and HON/sup +/ could be present in observable abundance in interstellar clouds. These species can be formed by the reaction of NO with H/sub 3//sup +/ but not by NO/sup +/ with H/sub 2/. Moreover, they are stable to dissociation and do not react with H/sub 2/ to re-form NO or to form isomers of HNOH/sup +/.
