目前,在一些综合的化学信息系统中,碳-13NMR数据库已经成为其中的重要组成部分。在我国,几年前,关于碳-13NMR数据库的检索还为一空白,现在,在逐步由研究阶段向实际应用阶段过渡。本实验室,首先在微型机上建立起了碳-13NMR数据库检索系统。在此基础上,又组建起了CIAC(Changchun Institute of Applied Chemistry)碳-13系统。这一系统虽然是建立在高档微型机上,但却具有大型计算机进行数据库检索的主要 At present, the carbon-13 NMR database has become an important part of some integrated chemical information systems. In our country, a few years ago, the search on the carbon-13 NMR database was still a blank. Now it is gradually shifting from the research phase to the practical application phase. The laboratory, first in the microcomputer to establish a carbon -13 NMR database retrieval system. On this basis, the CIAC (Changchun Institute of Applied Chemistry) carbon-13 system has also been established. Although the system is based on high-end mini-computers, but it has a large computer database retrieval of the main
