Abstract:

In our supersonic molecular beam sampling system the previously reported mass separation phenomenon was shown to be independent of temperature from 300 - 2200 deg K. Large quantities of polymeric species were observed in beams from simple gases at 1 - 7 atmospheres and at room temperature. Evidence is presented that these polymers are formed from supercooled gas in the process of condensing due to the extremely rapid cooling in isentropic expansion to high Mach number beams. The behavior of the anhydrous CO-O2, CO-N2O, and C2N2-O2 flames was studied at several dilutions. The CO-O2 flame was used in a preliminary study of the dissociation of Cl2 at 1600 - 20000 deg K to test the quenching efficiency of the sampling system.
