摘要
以Ｓａｄｔｌｅｒ标准ＮＭＲ谱图集为数据源．建立了烃类化合物ＮＭＲ谱化学位移数据库系统，并利用此数据库系统归纳出了烃类化合物各类碳氢原子族化学位移统计分布图，该统计分布图可用于指导烃类混合物．特别是石油产品ＮＭＲ谱峰的归属，同时，可提供一条查阅标准图的简捷途径．
In order to be sure of the specific chemical shift range for each hydrogen or carbon structural group,a database and managing system for NMR chemical shift of 725hydrocarbons published in Sadtler standard NMR spectra are established. With thisdatabase and managing system,statistical distribution charts of chemical shift for various hydrogen and carbon structural groups are given.NMR spectra of hydrocarbon,especially petroleum products can be analyzed with the above distribution charts.Thesystem can also be conveniently used to locate the standard spectrum.
