The relationship between 19F chemical shifts in halogenated propanes and their structures are elucidated using MNDO calculations to determine the population of rotamers. The pairs of atoms gauche to a fluorine atom and van der Waals interaction between the two terminal substituents are responsible for the 19F chemical shifts. The differences among chemical shifts in diastereomers are also discussed
使用MNDO计算确定了旋转异构体的数量,阐明了卤代丙烷中19 F化学位移与其结构之间的关系。氟原子对的原子对和两个末端取代基之间的范德华相互作用是19 F化学位移的原因。还根据分子的构象讨论了非对映异构体中化学位移之间的差异。
