Creator:: Hauswirth, William Walter
Abstract:: Fluorescence of adenine, guanine, thymine, cytosine, and uracil has been detected at room temperature in neutral aqueous solution using a digital signal accumulation technique and right angle fluorescence detection from solutions with absorbances between 0. 4 and 0. 7. The quantum yields are respectively 2.6 x 10⁻⁴, 3.0 x 10⁻⁴,...

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....

Creator:: Schwiebert, Maris Carol
Abstract:: The formation of cytosine hydroperoxide was detected in aqueous cytosine solutions irradiated with Co-60 γ-rays at pH 2. The nucleotide of cytosine, cytidylic acid, forms a hydroperoxide which was detected in neutral solution. The stability of the hydroperoxides of cytosine, thymine, and their nucleotides was found to be a function...

Creator:: Vernier, David L.
Abstract:: Triphenylmethyl dye cyanides have been known to be sensitive to ultraviolet radiation since early in this century. Under appropriate conditions, exposure to uv leads to heteropolar fission of the C-CN bond (photoionization) and intense coloration due to dye formation. Thin homogeneous films of hexahydroxyethyl pararosaniline cyanide in a nylon matrix...
