Abstract

Cisโ€1,2โ€dibromocycloheptane and cisโ€1,2โ€dibromocycloโ€octane and the corresponding trans dibromoโ€ and โ€dichloro compounds have been prepared. Dipole moments have been calculated from data on solutions of the compounds in benzene and in carbon tetrachloride. Infrared absorption spectra were taken from solutions in carbon disulphide. A short discussion is given comparing the results with those formerly obtained for the cyclohexane derivatives.

## Abstract ^13^C chemical shifts of more than fifty bicyclo[3.2.1]octane and bicyclo[2.2.1]heptane derivatives (hydrocarbons, alcohols, ketones and esters) have been determined. The usefulness of ethyl derivatives for the assignment of close ^13^C chemical shifts in bicyclic methyl derivatives is
