IRRAS spectra of NO/Cu(111) and ({radical}3 {times} {radical}3)R30{degrees} coverage of CO/Cu(111) in the range 3000--180 cm{sup {minus}1} show both the adsorbate internal modes and features assigned to the hindered rotational modes. These dipole-forbidden features are characterized by asymmetric (mostly negative) absorption lineshapes and are accompanied by a change in broadband absorption. The shape and intensity of this broadband absorption is well accounted for by a scattering model.
