The influence of coadsorbed alkali metal on the electronic structure of CO was studied by ARUPS with polarized and unpolarized light. A new peak at 6.3 eV was observed, it reflects a new orbital of CO with the presence of coadsorbed alkali atoms. A symmetry plane and an anti-symmetry plane for this orbital were found, which are paralell to the 〈001〉azimuth and 〈110〉azimuth of the crystal surface respectively. The symmetry results of CO coadsorbed with different kinds of alkali metal are the same.
