The formation of a defect lattice (DL) of a periodic orientational structure was investigated in the electroconvection of nematic liquid crystals. The investigation was performed on electroconvection in the nematic liquid crystal p-methoxybenzilidene-p′-n-butylaniline (MBA). The period of the DL perpendicular to the rolls was found to be equal to that of the domain structure in the abnormal rolls. The results show that the periodicity of the DL parallel to the roll is due to the beating mode of the normal rolls and the secondary mode.
