During the first few months of this project period, effort has been concentrated on the preparation of primary oxidants based on histamine, that is, molecules which will simultaneously adsorb to the surface of swollen polyethylene particles, ligate the Mg of chlorophyll, and accept an electron from photoexcited chlorophyll. The technique of measuring fluorescence yields in highly scattering samples has continued to be developed and improved. Fluorescence spectra and quantum yields for bacteriochlorophyll c in a number of solvents have been measured; the results are important for an understanding of energy transfer in green bacteria. 4 refs.
