摘要: 用360MHz超导核磁共振波谱仪测定了吗啡(morphine)和可待因(codeine)的质子耦合常数。用二维J-谱验证了一维质子谱的J-耦合。用一系列改性的Karplus公式计算了二面角(dihedral sngles),估算了吗啡和可待因的分子构型(configuration)。

Abstract: Coupling constants of morphine and codeine were obtained by using 360 MHz NMR. The coupling patterns were verified by a J-resolvcd two-dimensional spectrum. The dihedral angles were calculated by using a series of modified Kar-plus equations.The configurations of morphine and codeine were calculated from X-ray bond length and the calculated dihedral angles.
