We report on measurements of single molecule Brownian motion in liquid crystals unravelling the anisotropic mobility of individual dye molecules. This anisotropic Brownian motion is directly correlated with the structural properties in a smectic A (8CB) and a nematic (5CB) liquid crystal sample cell on the µm-scale using polarization contrast microscopy. A considerably slower mobility of dye molecules is found as compared to self diffusion measurements by NMR, while anisotropy values compare well to recent literature data. This is suggested to be related to local distortions of the director structure around the dye molecules.
