    Abstract

    The polarisation dependence of S K-edge NEXAFS has been used to study the adsorption geometry of SO2 on Ag(110). The molecular plane is azimuthally aligned along the [001] azimuth at 1/3 monolayer coverage, but rotated from [001] by about 55° at 1/2 monolayer, with the molecule upright at both coverages.
