✦ Synopsis

A low-power. low-field reaction yield detected magnetic resonance spectrometer is described. RYDMAR signals of photosynthetic reaction centres have been detected at microwave lields lower than 0.1 mT. It is concluded that the sum of the decay rate constants of the primary photoinducsd radical pair is less than 0.42&0.02 ns-'. and that the enchange interaction within the pair is between 0.1 and 1.0 mT.
