<jats:title>Abstract</jats:title><jats:p>The electronic band structure of systems with screw symmetry is developed using the smallest screw displacement as elementary operation. For atomic and molecular helical systems the resulting Hartree‐Fock SCF‐LCAO formulae are presented. Results for ferroelectric HC1 and HP are reported, obtained with the MUNICH‐CHAIN programme, in which the new formalism is implemented. The connection to the translational symmetry and the numerical results are discussed.</jats:p>
