We have observed, via time-of-flight mass spectrometry, 13 chemical species more massive than CS2 produced by shocking liquid CS2 to very high pressure/temperature. The stoichiometry of three of these species is uniquely determined from the 12CS2 exp

Numerous workers have suggested that the “A” parameter in the relation D(R)=D(∞)[1−A/R] is a measure of the steady-state one-dimensional chemical-reaction-zone length of a detonating explosive. This equation relates the steady-state detonatio

We report experimental observations of a chemically bound dimer of 2,4,6-trinitrotoluene (TNT) produced by high-pressure shock waves. The experimental observations were made with a time-of-flight (...

We report the measured failure diameter and a detonation speed for the liquid explosive mixture 90.5/9.5 wt % H2O2/H2O confined in thick seamless 304 stainless steel tubing and fired at ca. 30 °C. The detonation speed datum and knowledge of the diam

We report a time-of-flight mass spectroscopic study of the chemical reaction zone in base-sensitized detonating liquid nitromethane (NM--CH3NO2). Mass spectra of the reaction zone region are presented for cases where the CH3NO2, 13CH3NO2, and CD3NO2

We report experimental results concerning the occurrence and rate of the reaction CoCl2(EtOH)2 + 4EtOH → Co(EtOH)62+ + 2Cl- induced by transient high pressure. The experimental probe used to interrogate the system was time-resolved visible light sp

We report the production of a chemically bound dimer of anthracene produced by the shock compression of crystalline anthracene. The experimental probe used to detect the dimer structure was time‐of‐flight (TOF) mass spectrometry. The principal me

Semiempirical MNDO calculations of a symmetry-allowed dimerization of benzene are reported. The chemically bound C/sub s/ point-group dimer (o,p'-dibenzene) studies has the appearance of a 1,4-cyclohexadiene molecule bonded to 1,3-cyclohexadiene. The

The results of a uniform set of ab initio quantum-chemical calculations for 10 carbon/nitrogen cubanoids are presented. There are 22 possible C/N cubanoids with formulas (CH)[sub 8[minus]n]N[sub n], where 0 [le] n [le] 8. We give results for one cuba
