Sum frequency generation imaging microscopy is used to investigate self assembled monlayers on metal surfaces. In this study octadecanthiolate on gold, silver, copper, zinc, and steel are compared. The exposure of the surface to atmospheric corrosion is observed with the SFG imaging and local SFG spectra of the corrosion porducs are obtained.
