Abstract —The use of competitive methods with rubrene as reference acceptor provides values the rate constants k B Q = 2.3 times 10 9 / mol ‐1 s and v q 3.3 for physical quenching O 2 1 δg, by bilirubin (in CCl 4 ) biliverdin CHCl 3 respectively attributed to electron energy transfer processes. The constant R 1.7 8 reaction δg is considerably greater than that ‐ which has identical δa, sites, a primary Type I oxidation process followed slower II addition products.

Fires simultaneously burning in hundreds of square kilometers could result from a nuclear weapon explosion. The strong buoyancy field such large area fires induces high-velocity fire winds that turn upward the region. This results vertical transport quantity water vapor. We numerically model rise moisture-laden, free-convection columns and examine size increase clouds as function relative humidity, size, or heat release rate.

Abstract The photochemistry of an appropriately substituted bisimide has been studied in solution by conventional means and time resolved laser techniques as a model for the behavior inherently photosensitive solvent soluble polyimides, whose are not well understood. A mechanism photochemical insolubilization polymer systems is suggested based on results system, which confirmed studies polyimide solutions. Phosphorescence quenching rate constants compound indicate that triplet excited state...
