Abstract A numerical approach of physical behaviors in fluorinated liquid crystals has been investigated. The molecular parameters, such as dipole moment and polarizability were calculated using a semiempirical molecular orbital (MO) method. Using these molecular parameters and the Maier‐Meier theory, the temperature dependence of the dielectric anisotropy divided by the order parameter (Δ∍/S) has been estimated. In addition, taking the temperature dependence of the order parameter S into account, the temperature dependence of the dielectric anisotropy Δ∍ has been estimated. The calculated results are in good agreement with experimental results.
