✦ Synopsis

A detailed quantitative analysis of low-field RYDMR (reaction yield detected magnetic resonance) spectra of the photosynthetic bacterium Rhodobacter sphaeroides is presented. Reaction centres, in which the first stable electron acceptor (a quinone) had been pre-reduced, show pronounced temperature dependence around 280 K. This is interpreted in terms of a change in the separation of the constituents of the primary radical pair formed by photoinduced electron transfer.
