AbstractThe paper evaluates the possibilities and limitations in characterising photochemical properties of individual kinetically labile species being in mutual equilibrium. A model of calculating quantum yield values is elaborated and applied to azidokojic iron(III) complexes in aqueous solutions. Based on the known speciation of the complexes as a function of pH, Fe(III) and azidokojic acid concentrations, electronic absorption spectra of individual species, and the determined overall quantum yield of Fe(II) photoformation at irradiation with monochromatised radiation at 366 nm, the quantum yield of Fe(III) to Fe(II) photoreduction was obtained for each of the complexes present in the investigated systems.

Ultrathin Frozen Sections

During the last years it was shown that also by means of cryo-ultra-microtomy a good preservation of substructural details of biological material was possible. However the specimen generally was prefixed in these cases with aldehydes.Preparing ultrathin frozen sections of chemically non-prefixed material commonly was linked up to considerable technical and manual expense and the results were not always satisfying. Furthermore, it seems to be impossible to carry out cytochemical investigations by means of treating sections of unfixed biological material with aqueous solutions.We therefore tried to overcome these difficulties by preparing yeast cells (S. cerevisiae) in the following manner:
