【摘要】 研究了N,N’-邻硝基苯酰基取代苯酰氨基硫脲类化合物的芳环、碳硫双键和酰胺等的特征红外光谱,讨论了它们随化学结构而变化的一些规律,特别详细讨论了不同取代基对远程基团特征光谱的影响。结果表明距离取代基直至第五个基团的特征谱带仍然受到影响,并且供电子基所处位置对远程基团特征光谱影响较少,而吸电子基所处的位置影响较大。这对该类化合物和远程光谱的研究是很有启发意义的。更多还原

【Abstract】 The characteristic infrared spectra of N-o-nitrobenzoyl-N’-substituted phenylacylthiosemicarbazides were studied and how they change with the change in chemical structure discussed. Specially, the effect of different substitute on the characteristic infrared spectra of long-range radical was discussed in detail. Results show that characteristic bands of the radical which is as far as five radicals away from substitute group are still affected, the seat of electron contributing group makes little affection, while the electron withdrawing group does differently, which has very suggestive meaning for the study of these compounds and long-range spectra research.更多还原
