摘要: Abstract Structure and transition behavior of zinc(II) stearate crystal were investigated by infrared XAFS spectroscopies. zinc at room temperature was estimated as follows. From analysis, the coordination number carboxylate groups around atom evaluated 4 ZnO distance 1.95 A. Based on spectrum a normal mode conformation alkyl chain confirmed all- trans sub-cell packing considered parallel type, also form determined bridging bidentate type. As increasing temperature, has solid–liquid phase 130°C. At transition, chains goes into liquid like state reported Mesubi but structure to be maintained.
