✦ Synopsis

Dipole Moments and Conformation of 3‐ and 4‐Bromo and Chloro Heteracyclohexanes

The dipole moments of some 3‐ and 4‐bromo and chloro heteracyclohexanes are measured by the method of Debye and calculated both by the quantum‐mechanical method CNDO/2 and vector addition method.

The determination of conformational free energy is made on the basis of measured dipole moments μ of the conformation mixture and the calculated dipole moments μ~e~ and μ~a~ of the pure conformers. The results are discussed in relation to n.m.r.‐results.
