Surface second harmonic generalion (SHG) has been developed as a surface specific type or electronic spectroscopy. The surke second-order susceptibility x(" is enhanced by the adsorption 01 molecules. and an elsctronic spcc~rum an be gcncnred by scanning thz dye laser through Ihe wo-photon resonance
