In this work, photofragmentation translational spectroscopy and 1st principles electronic structure theory reveal the literature value of the heat of formation of chlorine-isocyanate to be in error by more than40kcal∕mol. We report a revised experimental value forD0(Cl–NCO)=51±3kcal∕molwhich ...
Heats of formation and dipole moments of chlorofluoromethanes are shown to be accounted for quantitatively with an electrostatic model. Initial point charges are placed at infinite distance, and the atoms are moved to molecular dimensions and allowed to polarize. If the heat of formation of the ...

Although it is used extensively (with great caution), ClO2 is a dangerous explosive having a heat of formation of +105 kJ mol−1. When ClO2 is photolyzed at −78 °C, it apparently yields Cl2O3 as one product. The structure of the Cl2O3 molecule is Sign in to download full-size ...
Chlorine containers should not be stored near a heat source, anhydrous ammonia, hydrocarbons, or any chemicals with which it could react violently. In the event of a container leak or a liquid spill, water should not be sprayed directly on to the liquid. Doing so will increase the ...
boots and saddleA U. S. Army bugle call for mounted drill and formation. This expression denoting a cavalry trumpet sound is a corruption of the Frenchboutes la selle‘put on the saddle,’ and consequently has no semantic relationship withboots. However, since boots are logically associated wit...
Surface analysis of heat-treated Mong Hsu rubies Mong Hsu rubies have been heat treated in air at 1100, 1200, 1300, 1400, 1500 and 1600 °C. Their visual appearance and surface analysis (XPS) after each s... S Achiwawanich,N Brack,BD James,... - 《Applied Surface Science》 被引量...
Chlorine-hydrogen mixture can explode in the presence of sunlight, heat or a spark. Also, it can explode when mixed with acetylene or diborane at ordinary temperatures, and with ethylene, fluorine, and many hydrocarbons in the presence of heat, spark or catalysts. ...
