摘要: 本文叙述了用计算机辅助解析C-13 NMR谱。系统中利用经验参数预测饱和碳化学位移方法,并使取代基参数增至45个之多。无环烃类脂碳位移计算结果与实测值基本一致,脂环碳位移尽管计算准确性略低,但也是可实用的。本程序不仅计能算脂碳化学位移,而且对某些含碳功能团位移也可给出估算值。该程序用FORTRAN、BASIC两种语言编写,可分别在PDP11/23和IBMPC/XT机器上运行。

Abstract: In this paper a method based on additive C-13 shift relationships, using empirical substituent chemical shift paremeters, is described. It is applicable to aliphatic saturated hydrocarbons earring 45 functional groups as well as the carbons contained in these functional groups. It can also take care of alicyclic compounds, although it's accuracy tends to be lower. The computer program is written in FORTRAN IV-plus and BASIC, and run on a VAX 11/780, or a PDF 11/23, or a microcomputer IBM PC/XT etc.
