theoretical model based on valence–bond theory is also proposed and used to analyze the effects of the nuclear configuration corresponding to each frozen tautomer structure. In the present case, the aromatic form and the allylic‐anion‐like system of the NCN group inherent to each isomer are crucial for understanding and analyzing the different responses of each “blocked” tautomer.
本文详细介绍了由N-ac啶取代的2-氨基苯并噻唑衍生的“封闭的”氨基亚氨基互变异构体及其对非线性光学响应的影响。这些冷冻互变异构体的合成,表征和非线性光学性质,即N-甲基-N- (2-硝基ac啶-6-6基)-2-氨基苯并噻唑和3-甲基-N- (7-硝基ac啶-3 -yl)-2-亚氨基苯并噻唑的报道。还提出了基于价键理论的理论模型,并用于分析与每个冷冻互变异构体结构相对应的核构型的影响。在当前情况下,芳族形式和烯丙基阴离子的像的系统 Ñ Ç Ñ 每个异构体固有的基团对于理解和分析每个“受阻”互变异构体的不同反应至关重要。
