CO+Cs/Ru(101-0) system has been investigated using HREELS. Two molecular adsorption states of CO were found. One with higher C—O frequency was similar to that on clean Ru(101-0) surface, while the other with lower C—O frequency appears on a Cs-precovered Ru(101-0) surface. Two states of CO were occupied sequentially during the exposure to CO. The frequencies of both two loss peaks shift to higher values with exposure to CO and to lower values with higher Cs precoverage.
