Abstract The low resolution microwave spectrum of N-nitro,N-methylaniline shows only one series of μa R-branch bands. The value of B + C = 1584.6 MHz is consistent with this being the rotamer in which the benzene ring is exo to the nitroso group. The high resolution microwave spectra of the normal. CD3 and two meta-D species show conclusively that this rotamer has a non-polar heavy atom skeleton. The
摘要 N-硝基,N-甲基苯胺的低分辨微波光谱仅显示出一系列μa R-支带。B + C = 1584.6 MHz 的值与苯环在亚硝基外的旋转异构体一致。正常的高分辨率微波光谱。CD3 和两个元 D 物种最终表明该旋转异构体具有非极性重原子骨架。基于苯胺和N,N-二甲基亚硝胺结构的分子模型很好地再现了旋转常数、量Δc(= Ia + Ib - Ic)和取代坐标,其中苯环平面扭曲了≅相对于分子其余部分的重原子平面成 30°。
