摘要：
The relationship between F-19 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 F-19 chemical shifts. The differences among chemical shifts in diastereomers are also discussed in terms of the conformation of the molecule.
