Quantitative estimations, that is, in what percentage of the centers the iron is completely absent, are currently pursued by temperature-dependent Mössbauer spectroscopy.

    • The Euler angles are defined according to Mathews, J.; Walkers, R. L. Mathematical Methods of Physics; W. A. Benjamin, Inc.: New York, 1970; p 404; that is, a is a positive rotation about Z axis, ß is a positive rotation about Y′ axis, and y is a positive rotation about Z′ axis.

    • note
    • - iron-depleted PSII published in refs 13 and 22 closely resemble the spectrum in Figure 4 for pH 5.8. This similarity between the ESEEM the high pH-treated PSII with the spectra in PSII samples where the iron is known to be absent corroborates the view that, in high pH-treated PSII, the iron is also absent.
