The deficiency of spectroscopic binaries among Ap stars compared with normal stars is confirmed. In systems with Ap components of other than Mn‐Hg type we have a lack of short periods. For these systems we have established relativ large excentricities of their orbits. Circular orbits are absent. These observational facts must be taken into consideration in order to explain the generation of stellar magnetic fields and Ap characteristics.
