This paper reviews recent progress in the field of hydrogen production by photosynthetic water splitting for both in vitro and in vivo systems. Absolute thermodynamic efficiencies of conversion of light energy into energy of molecular hydrogen by intact m...
A method for the production of t-butoxy radicals by the photolysis of t-butyl hypochlorite was employed to determine the absolute rate of combination of t-butoxy radicals at room temperature and to determine the absolute rate of hydrogen atom abstraction ...
The reaction of tert-butoxy radicals with diphenylmethanol and with cumene was examined using nanosecond laser flash photolysis techniques in order to determine the absolute values of the rates of reaction of the radicals. The absolute rate measured for both substrates compare favorably with the values for the ...

The analysis shows that a rectangular hyperbola equation - used by McCree to describe the photosynthetic rate as a function of light intensity - is valid only in a limited range and that an extrapolation will give too high a photosynthetic rate. An expone...
