    Abstract

    The accurate determination of lattice parameters of small colloidal Pt particles in solution can be accomplished by EXAFS analysis. Thus, it could be demonstrated that a lattice contraction (0.4 %) takes place in the transition from the metal to the colloidal state. The results of the EXAFS investigations supplement those obtained by high‐resolution electron microscopy (HREM). The diagram on the right shows a typical HREM photograph of a colloid particle with perfect cubic face centered lattice. (Figure Presented.)
