Produktbeschreibung

Rooted in the crystal structure of the reaction center of meanwhile two bacterial organisms, the present compilation of invited papers points in a self-evident way to the different lines of developments in a still vividly expanding field. The abundance of open questions initiated also novel methodological approaches spanning a wide bow from biochemistry and genetic engineering over complex spectroscopies to chemical modelling, molecular dynamics calculations and electron transfer theory.
