The flexoelectric coefficients e1 and e3 for polar liquid crystals, such as 4-n-pentyl- $4^{\prime }$-cyanobiphenyl, are investigated theoretically by means of an integral equation approach, which takes into account translational, orientational correlations as well as their coupling. e1 and e3 are evaluated from microscopic expressions derived on the basis of a density-functional method.
