摘要：

The PMR spectrum of 2,7,8-trioxa-1-phosphabicylo[3.2.1]octane (I) has been fully analysed by the first order assumption and a preferred conformation of the molecule was determined on the basis of the coupling constants. Many 4J (long-range coupling through four bonds) were observed both in the coplaner and non-coplaner systems. An unexpected 5J was observed, which can be considered as a through-space" long-range coupling. Attention has been directed also to the angular dependency of JPOCH and JPOCCH. © 1969."
