yields two transient species, an alkoxy radical and an aromatic radical cation.
Warner says, "The thymines seek each other out and hold each other in place to make the photoreaction
Another patient who was patch tested and photopatch tested had a strong photoreaction
to benzophenone-3 at day 7.
The behavior of the intermediate hosts of Acanthocephala, arthropods, may show various changes when infected, including changes in activity, photoreaction
, escape behavior, substrate color choice, and vertical distribution (e.
2] is not only to provide a catalyst to enhance the photoreaction
between PQ and MMA molecules via the Zn ions in the Zn[(MA).
alkoxyl and peroxyl radicals) whereas the predominant photoreaction
of the lipophilic Bcarotene might be the scavenging of excited species such as singlet oxygen and triplet states.
then proceeds to yield an enantiomeric excess of one stereoisomer.
Norrish Type I ([alpha]-cleavage) in the excited triplet state was the predominant primary photoreaction
in this experiment.
Although the ability to perform this photoreaction
of 2-undecanone may not itself prove of practical importance, Guillet says the work demonstrates the principle of using solar energy to carry out organic chemical reactions in water.
We also chemically analyzed the products of the laser-induced photoreaction
using a microscopic UV-Vis spectrophotometer, a microscopic FT-IR, mass spectrometry, GPO and NMR.
The chain growth of conjugated polyene sequences in PVC is a well-studied photoreaction
whose depth dependence is controlled by the subsurface availability of oxygen.
