Metastable and collision-induced dissociation studies of unimolecular and bimolecular reactions in the C/sub 2/H/sub 5/O/sup +/, and C/sub 2/H/sub 8/N/sup +/ systems: the role of CH/sub 3//sup +/ radiative association reactions in interstellar clouds
Studies of the C/sub 2/H/sub 5/O/sup +/, C/sub 2/H/sub 7/O/sup +/, and C/sub 2/H/sub 8/N/sup +/ system are reported. Studies of the unimolecular metastable reactions provide information on the lowest energy dissociation pathways and the potential barriers to the reverse association reactions. Collision-induced dissociation is used to investigate the structures of C/sub 2/H/sub 5/O/sup +/, C/sub 2/H/sub 7/O/sup +/, and C/sub 2/H/sub 8/N/sup +/ ions formed in a number of association reactions: CH/sub 3//sup +/ associates with CH/sub 3/OH to yield CH/sub 3/OHCH/sub 3//sup +/. H/sub 3/O/sup +/ and C/sub 2/H/sub 4/ yield CH/sub 3/CH/sub 2/OH/sub 2//sup +/; NH/sub 4//sup +/ and C/sub 2/H/sub 4/ give CH/sub 3/CH/sub 2/NH/sub 3//sup +/; and H/sub 3/O/sup +/ and C/sub 2/H/sub 2/ result in CH/sub 3/CHOH/sup +/. The results indicate that CH/sub 3//sup +/ IR radiative association reactions will not contribute to the formation of C/sub 2/H/sub 5/O/sup +/, C/sub 2/H/sub 7/O/sup +/, and C/sub 2/H/sub 8/O/sup +/ ions in interstellar clouds. However, the association reactions of H/sub 3/O/sup +/ and NH/sub 4//sup +/ may be important in interstellar clouds. 18 references, 7 figures, 2 tables.
