Figure 12
Structures of 4-bromophenylalanine (left) and 3,5-dibromotyrosine (right) with parameters of the refined simulations of Figs. 10(c) and 10(d), respectively; all atoms were included in multiple-scattering units whose occupancies refined to 1.0 for both spectra. Distances in Å, Debye–Waller-type factors quoted as 2σ2 in Å2 in parentheses. 4-Bromophenylalanine: energy range, 25–635 eV; ΔEF, −2.162 eV; fit index (k3-weighting), 0.1324. 3,5-Dibromotyrosine: energy range, 25–635 eV; ΔEF, −3.186 eV; fit index (k3-weighting), 0.1981. |
