Structured emΓ―ssion spectra have been observed in tbe wavelengtb range 470-720 & from the reaction of oxygen atoms wΓ―tb tetrafluoroetbylene. The emΓ―ssion is tentatively assigned to the CF2eBI) + CFz(t At) phosphorescence tiansition. The excited singlet CFz('Bt) is also formed through the triplet-Mp:

of acetone-d6 and tetrnmethyl-ethylene (ThlE) yields acelone and T?AE-d6 as the only products. The comparable behavior of this reaction and the transfer of triplet excitation energy from aGetone to olefins points to a common molecular triplet oxetane intermediate for both processes.

The quantum yield of the photochemical reaction of the benzophenone group, either free or bound to a macromolecular chain in polyvinylbenzophenone, with a proton donor (isopropanol) has been measured in the absence and in the presence of an efficient triplet acceptor (Ferrocene), either free (extern
Numerical experiments were carried out to determine the timewise self-consistency of different physical processes involved in the energy transfer in green plant photosynthecc units. A 6 X 6 X 6 array of chlorophyll-a with cubic lattice constants a = b = c = 20 A was chosen as a model of the thylakoi
Micro-mixing calculations based upon a simplified non-deforming one-dimensional diffusion-reaction formulation are presented for the sequence of three reactions denoted by A + B -R + B -S + B + T. This triplet reaction under micro-mixing is posed as five simultaneous parabolic partial differential e
