Abstract

We have measured high-resolution x-ray absorption spectra of lanthanide (Ln) and heavy transition metal complexes that display prominent narrow absorption peaks near the L2 and L3 absorption edges. The anomalous scattering factors (f' and f"), which are mathematically related to the absorption cross section, have correspondingly sharp changes in their magnitude within 5-10 eV of the absorption edge. Calculations of the magnitude of the change in f' and f" demonstrate that significant changes (on the order of 20 electrons in f') can be expected for these materials. These substantial changes in the anomalous scattering factors have applications to deriving structural information for macromolecules from x-ray diffraction studies. The magnitude of the changes indicate that the anomalous scattering technique is a powerful means of obtaining structural characteristics for macromolecules in single crystals, in solution, and in biological membranes.

摘要

我们测量了镧系元素(Ln)和重过渡金属配合物的高分辨率X射线吸收光谱,这些配合物在L2和L3吸收边附近显示出突出的窄吸收峰。与吸收截面数学相关的反常散射因子(f'和f")在吸收边的5-10 eV范围内其大小相应地有急剧变化。对f'和f"变化幅度的计算表明,这些材料有望出现显著变化(f'变化约20个电子)。反常散射因子的这些显著变化可应用于从X射线衍射研究中推导大分子的结构信息。变化幅度表明,反常散射技术是获取单晶、溶液和生物膜中大分子结构特征的有力手段。
