The reaction between O-ions and F centers

Creator:: Staible, Thomas Fredrick
Abstract:: The photochemical reaction between O⁻ ions and F centers was investigated. The activation energy was determined by the Arrhenius law to be 0.10 + 0.04 eV for temperature below 180°K. The diffusion of alpha centers towards the oxide ion was eliminated as the rate limiting step and the low trapping...

The photodecomposition of t-butyl bicyclo [7.1.0] decane-2-percarboxylate

Creator:: McRitchie, Donna Louise
Abstract:: This paper describes the synthesis of t-butyl bicyclo[7.1.0] decane-2-percarboxylate and its photolytic decomposition. The title compound was found to undergo simple homolytic cleavage when exposed to light of 2537 A; producing the cyclodecyl radical, carbon dioxide, and t-butoxy radical. The largest percentage of products arose from an intimate radical pair...

A study of the photolysis of the aqueous thymine system at 214 nm, 229 nm and 254 nm

Creator:: Satcher, Robert Lee
Abstract:: The photolysis of the aqueous thymine system has been investigated at 214 nm, 229 nm and 254 nm at room temperature. Products of photolysis have been identified as hydrogen peroxide, 6-hydroxy-5- hydroperoxy thymine and tentatively 5-hydroxy-6-hydroperoxy thymine. These together with thymine loss, were determined quantitatively under a variety of conditions....

Fungal growth responses to a photooxidized sodium ligninsulfonate

Creator:: Rockhill, Robert Clayton
Abstract:: Sodium ligninsulfonate, a water soluble wide-range molecular weight polymeric by-product of the paper pulping industry, is added as waste effluent to water ways or burned, causing extreme pollution. The polymer is highly resistant to biodegradation. Therefore, modification of the structure to a more readily biodegradable form would be desirable, to...

The photochemistry of some insect juvenile hormone analogs

Creator:: Siggel, Lorenz
Abstract:: The photochemistry of some analogs of insect growth regulators (IGR's) was studied. Methyl geranate, TY, was synthesized and the mechanisms of its photochemical reaction pathways were studied by a variety of techniques. Direct irradiation of 71 in ether leads to the formation of five new products: 98, the product of...

Transient optical absorptivity of nitrogen dioxide following pulsed illumination

Creator:: Murray, John Sutherland
Abstract:: A knowledge of the time rates for intermediate reactions during the photolysis of nitrogen dioxide enables one to deduce the possible intermediate reactions which are responsible. An experiment has been devised and constructed which will measure the time rates for photochemical reactions occurring in ranges of one micro second to...

The photochemistry of polychlorobenzenes in micellar media

Creator:: Lee, Youn-Sik
Abstract:: Photolysis of pentachlorobenzene was carried out in the absence of an electron donor species at 254 nm in cetyltrimethylammonium bromide surfactant solution. The results are consistent with the excited triplet undergoing homolytic cleavage of a C-Cl bond in competition with formation of the excimer, in which the radical anion undergoes...
