Abstract
Far infrared (IR) spectra of the surface films on copper have been obt ained ''in situ'' in aqueous solution environments using a synchrotron source. The oxide film on copper at 0.05 V vs. SCE in 0.1 M NaOH solu tion has been identified as Cu2O. In the passive region at 0.3 V, CuO and Cu(OH)(2) appear to be present on the surface. In dilute solutions of KOCN in perchlorate, vibrational bands have been observed that cou ld be attributed to a few monolayers of Cu(OCN)(2). (C) 1997 Published by Elsevier Science B.V.
