Abstract

A comparative analysis of the P700⁺ electron spin echo modulation in preparations containing normal and heavy water has permitted the detection of the deuterium resulting from isotopic substitution in the immediate surroundings of the P700 centers. The contribution to the modulation is made by a single nucleus coupled with the unpaired electron with the anisotropic hyperfine interaction T_⊥ = 0.4 MHz.
