Raman microscopy has been used to characterize the interlayer anions in synthesized hydrotalcites of formula Mg 6 Al 2 (OH) 16 (XO 4 )•4H 2 O, where X is S, Mo or Cr. The Raman spectrum shows that both the chromate and molybdate anions are not polymerized in the hydrotalcite interlayer. This lack of
## Abstract Let __K(p, q), p ≤ q__, denote the complete bipartite graph in which the two partite sets consist of __p__ and __q__ vertices, respectively. In this paper, we prove that (1) the graph __K(p, q)__ is chromatically unique if __p__ ≥ 2; and (2) the graph __K(p, q)__ ‐ __e__ obtained by del
