The bonding features and three dimensional structures of metal clusters on single crystal oxide surfaces can be determined by the polarization dependent total reflection fluorescence XAFS (PTRF-XAFS) method. K-edge XAFS has a cos<sup>2</sup> θ polarization-dependence to give successfully three dimensional structure while L<sub>3</sub> edge XAFS has a weaker polarization dependence though the L<sub>3</sub> edge is suitable for Au and Pt samples. In order to overcome this issue, we have developed an angle-resolved total reflection fluorescence XAFS (ARTRF-XAFS) method to determine more precise three dimensional structures of Au clusters using the L<sub>3</sub> edge by increase the number of data points. In this paper we described the methodologies of the ARTRF-XAFS and the results of Au clusters on the TiO<sub>2</sub>(110) surface.
