摘要
本文对通式为(其中R′为或R为-CH_2、-CH_2CH_3、一CH_2CH_2CH3、-CH(CH_3)_2、-CH_2C_6H_5、-CH_2CH=CH_2或的10种含氮有机物进行了核磁研究,记录了其~1H NMR谱,确定了各~1H的化学位移和~1H与~1H之间的耦合常数,并讨论了核磁参数与结构的关系。
In this paper a nuclear magnetic study of ten organic compounds contai-ning nitrogen, whose formula is R'??NR(in which R' is ??R is -CH_3,-CH_2CH_3,-CH_2C_6H_5,-CH_2CH=CH-2 or-CH_2??CH_2CH_3)are made and their ~1HNMR spectra are recorded. The ~1H chemical shift and ~1H-~1H co-upling constants are determined, and the relation between nuclear magnetic constants and their structures are discussed.
