1H NMR中d=8.15ppm和d=7.31ppm附近分別有兩個(gè)雙重峰,這是苯環(huán)相鄰兩個(gè)氫的耦合產(chǎn)生的,且兩者個(gè)數(shù)相等,都是12個(gè)H. d=10.19ppm為伯胺H的化學(xué)位移,在d=7.31ppm 和7.10ppm 是苯環(huán)上H的位移,各有一個(gè)雙重峰,表明苯環(huán)上對(duì)位的硝基全部被取代了。 |

| In 1H NMR there exists two double peaks with the same H of 12 produced by coupling of two adjacent H on benzene at diameter of 8.15 and 7.31 ppm. Diameter of 10.19 ppm is chemical shift of H of primary amine. There exist two double peaks that belong to H on benzene at diameter of 7.31 and 7.10 ppm,indicating that contrapuntal nitro on benzene is replaced. |

| 1H NMR spectrum showed two doublets around d=8.15ppm and d=7.31ppm, respectively. They were yielded from coupling of two neighboring H on benzene, both of which with 12 H. d=10.19 ppm indicates the chemical shift of H on primary amine, whereas d=7.31 ppm and 7.10ppm is the H shift on benzene. The presence of doublet at each shift indicated that contrapuntal nitro on benzene is substituted. |
