1·Their rotatory direction and optical rotation are determined by the molecular stereostructure.
它们的旋光方向和旋光度大小都是由其分子的立体结构所决定。
2·Their rotatory direction and optical rotation are both determined by the molecular stereostructure.
它们的旋光方向和旋光度大小都是由分子的立体结构所决定的。
3·The raceme, the (R)-isomer and the (S)-isomer are identical in chemical structural formula but different in stereostructure and optical rotation performance.
