SYSTEM OF CRYSTAL STRUCTURE ANALYSIS ON PCCOMPUTER——NOMCSDP PACKAGE

The package of crystal structure analysis---NOMCSDP (NaturalOrganic Molecule Crystal Structure Determination Package)Version 1.0 has been devel-oped on the widely used IBM PC computer. It can perform the whole task of X-raycrystal structure analysis, as well as can be used for computing crystal structure onneutron diffraction. NOMCSDP has many advantages--easy operation, less needs forspecialized crystallographic knowledge, wide applicability of solving structure, and havingall the necessary functions. The inexorable trend of X-ray crystal structure analysis in thecourse of realizing the wide spread use in determining molecular structure of natural productswas discussed and the pratical uses of NOMCSDP were illustrated with examples. We hopethat this version will play active role in the process of promoting routine use of crystalstructure analysis.
