Enraf—Nonius CAD4 single crystal X-ray diffractometer with point detector
The use of X-ray structural analysis to study the structure of materials, in the Institute ‘Vinča’ began in the early 50s of the last century. Studies of monocrystal structures have been performed using the film technique, but soon the scope of research has been widened by the installation of powder diffractometer. Significant for this period is relatively early availability of computer hardware and software for the processing and analysis of experimental data. Particularly important for development of X-ray structural studies at the Institute ‘Vinča’ was the work of Rajna Herak and Bogdan Prelesnik. Apart from the research in the field of crystallography and structural chemistry, they have made a significant contribution to the education of young researchers. Thanks to their efforts, at the end of the 80s of the last century, Laboratory for Condensed Matter Physics in the Institute ‘Vinča’, was equipped with automatic four-circle diffractometer which had great significance for the further development and application of X-ray structural investigations in Serbia. Current single crystal studies in the Institute ‘Vinča’ are focused mostly on the intermolecular interactions and its role in the aggregation of molecules in the solid state. These research activities include also application of various statistical and computational methods in the studies of structural correlations. Particulary significant for these studies, are high resolution experiments at low temperatures, which are carried out mostly through the international cooperation.
