Molecular Synthesis

Rate constants and product distributions have been determined for ion/molecule reactions of cyanoacetylene (HC3N) with He+, C+(2P), CH3+, C2+, C2H+, C2H2+, CN+, C2N+, C2N2+, N2+, CO+, H3+, N2H+, HCO+, C2H3+, H3O+, CH3NO2H+, CH3CNH+, (CH3)2COH+, i-C3H7OH2, C3H+, and C4N+. The measurements were performed with the selected-ion flow-tube (SIFT) technique at 296 ± 2 K. The observed reactions exhibit a variety of pathways including charge transfer, proton transfer, condensation, and association. The condensation and association reactions are suited for molecular growth by ion/molecule reactions. Special consideration is given to the active role of cyanoacetylene in the possible molecular synthesis which occurs in dense interstellar gas clouds by ion/molecule reactions.

The apparatus described will shear bulk materials at strain rates from 2 × 10−5/sec to 5 × 10−1/sec while the materials are under nearly hydrostatic pressures. This apparatus gives complete stress-strain curves in the plastic region at pressures from about 10 kbar to approximately 80 kbar. Data on beryllium are given as an example of the type of data available from this apparatus.

Charge Transfer Model

A Selected-Ion Flow Tube (SIFT) apparatus has been used to produce Xe+ by electron impact and to study its reactions with C2N2. The 2P3/2 and 2P1/2 spin states of Xe+ were observed to react differently: by C2N2 addition to form Xe+•C2N2 and by charge transfer to form C2N2+, respectively. Further ion–molecule reactions with C2N2 were observed to establish polymeric ions of the type (C2N2)x+. The results indicate that the simple charge transfer model may be sufficient to account for the rate enhancement observed in the radiolytic polymerization of C2N2/Xe mixtures.
