Shock-Induced Chemical Reactions in Condensed Matter.
Abstract
Some background information is given on fast reactions, detonations, shock waves. Research at Washington State University on liquid CS2 is summarized. Techniques for and results of measurements of characteristic reaction times are given in Section IV. A double shock method was used, a double wave observed, and times ranged from less than 10 nsec at 150 kb to several hundred at 80-90 kbars. An induction time was observed in some experiments and a quasi-coherent electrical signal appears to have generated in the reaction process. Reflection and absorption spectroscopy are reported in Section V. Reflection measurements show that the shocked liquid behaves like a poor conductor in the spectral range 2500-4000 A for shock pressures greater than about 20 kb. Transmission measurements show that extinction extends into the visible as shock pressures increase. The shift is linear with pressure about 20 kbars, but the dependence is more complicated at higher pressures. The observations do not appear to be compatible with static pressure and temperature measurements, but this observation requires further substantiation. (Author)
