符号关系式在测定含重原子晶体结构中的应用——Ⅱ.分量关系式及其应用

作者在前文中指出了符号关系式法和重原子法相结合的可能性,并提出了一个利用符号修正过程来代替电子密度逐次迫近的方案。本文在前文的基础上进一步探讨了非中心对称情况下,将上述方法和同晶型置换法或反常散射法等相结合的问题。

THE USE OF SIGN RELATIONSHIP IN THE DETERMINATION OF HEAVY ATOM CONTAINING CRYSTAL STRUCTURES——II. "COMPONENT RELATIONSHIP" AND ITS APPLICATION

In Part I of this article, the possibility of combining the "heavy atom method" and the "sign relation method" has been pointed out, and a sign-refinement procedure has been suggested to replace the ordinary successive electron density syntheses. The present part deals with the problems concerning the combination of the procedure previously suggested with the isomorphous replacement method or anomalous scattering method in the case of noncentrosymmetric crystals.
