Solution X-ray scattering measurements, which make use of the power of synchrotron radiation, have now added important elements to the picture. Closed and open structures give significantly different scattering profiles (Fig. 12), especially in the medium angle range (104). These studies have shown that the opening of the N-lobe of apolactoferrin seen in the crystal structure is consistent with the solu-...

Aqueous solutions of molybdate and arsenate, pH 3-5, contain [AsMo903i(H20)3]3 and an As2Mo6 anion.71 The exact structure of the latter ion in solution is in some doubt, although the tetramethylammonium sodium salt contains the anion shown in Figure 15. Low angle X-ray scattering measurements of aqueous molybdoarsenate solutions are not compatible with this structure and the anion may be hydrated in a fashion similar to that observed for the analogous... 

SAXS (Small Angle X-ray Scattering) measurements provided further insight into the structure of the assembly in solution [70]. Using the GNOMN/DAMMIN software packages, the SAXS data were used to reconstruct a low resolution three-dimensional particle shape (yellow semitransparent spheres in Fig. 19) [71-74]. 

X-ray scattering measurements, Raman, and IR spectroscopy on aqueous solutions containing Zn + and Br ions show that the highest complex formed is tetrahedral... 

Using X-ray scattering measurements, Toney and co-workers obtained experimental information about the density of water molecules in a weak electrolyte solution near charged Ag(lll) surfaces. These results were somewhat controversial, because they indicate the presence of three to four dense layers of water as well as distinct solution structures for negatively and positively charged surfaces. Nonetheless, the layering proposed by those authors is at least superficially similar to that derived by simulations. (We return to the discussion of these results later when simulations under electric fields are considered.) It would be useful to have additional experimental results for uncharged surfaces.

Fig. 25 A representation of the in-plane X-ray scattering measured at —0.13 V in solution containing 0.1 M HCIO4 - -10 M Cu + -I-10 M KBr. The solid circles correspond to the measured c(2 X 2) reflections and the squares to the location of bulk Pt CTRs and Pt Bragg reflections. The lower figures show scans through the indicated reciprocal lattice points at (a) (1/2, 1/2, 0.1) (b) (0,1,0.1) and (c) (1/2, 3/2, 0.1). In each case, the solid lines are fits of a Lorentzian lineshape to the data.

Cu-Br structure on Pt(lll) x-ray scattering measurements. In this section, we present some x-ray scattering measurements of the Cu UPD layer on Pt(lll) in a solution containing bromide anions. Selected results are summarized in Figure 7.
