摘要：
The electronic structure of H2S adsorbed on the goethite (110) surface has been studied by ASED- MO cluster calculations. We have studied both the perpendicular and the parallel H2S molecular adsorption on the FeOOH(110) surface. We have analyzed the adsorption con. guration energies including rotation. The parallel species does not rotate during adsorption and corresponds to the most stable con. guration. We have also studied the bonding contributions for the minimum energy con. guration and the density of states plots.
