The n.m.r. spectra of series of 4-substituted-2-nitrophenyl acetonyl sulphides, ethyl sulphides, benzyl sulphides, and ethyl disulphides and of some ethyl 4-substituted-2-nitrobenzenesulphenates have been measured. The frequencies of the methyl and methylene protons give a good correlation with the Hammett σ-constant (r>0·990). Transmission factors of 0·67 ± 0·07, 0·60 ± 0·09, and 0·69 ± 0·16 were
已经测量了一系列的4-取代的-2-硝基苯基丙酮基硫化物,乙基的硫化物,苄基的硫化物和乙基的二硫化物,以及一些4-的取代的2-硝基苯的甲基苯磺酸盐的核磁共振光谱。甲基和亚甲基质子的频率得到具有哈米特一个良好的相关性σ的常数(- [R > 0·990)。对于–CH 2 –,– S–和–O–分别获得了0·67±0·07、0·60±0·09和0·69±0·16的传输因子。关于先前记录的值讨论了这些值。
