The weak electrostatic interaction between nitro and carbonyl moieties has been observed by means of variable‐temperature NMR spectroscopy. Its energetic contribution was evaluated to be about 3 kcal mol−1 by DFT calculations, and confirmed by the measurement of internal energy barriers to the rotation of suitable nitroaryl rings.
硝基和羰基部分之间的弱静电相互作用已通过可变温度NMR光谱法观察到。通过DFT计算,其能量贡献被评估为约3kcal mol -1,并且通过测量对合适的硝基芳基环的旋转的内部能垒来证实。
