Abstract:Resonance Raman spectra of the π-cation of bacterio-chlorophyll a in solution at 30 K are reported and discussed. Outer C
/></figure>C bonds of the pyrroles and the methine bridges are weakened by the ionization, while C<figure class=/></figure>N and Mg-N bonds remain essentially unaffected. Resonance Raman spectra of reaction centers suggest that the positive charge on <em>P</em>-870<sup>+</sup> should be localized on a single bacteriochlorophyll molecule by the lifetime of the scattering process (≈ 10<sup>?13</sup> s).</td>
