21. Dielectric screening effects are unlikely to affect the ITF values for the mixed NO/CO adlayers anyway on Ir(111) since, as noted in the text, CO removal is apparently accompanied by NO clustering, so that the degree of screening is likely to be largely unchanged. A more significant effect is possible on Ir(110), however, since the NO molecules are surrounded largely by water after CO removal; the smaller electronic polarizability of water should diminish the dielectric screening effect [see Refs. 6 (a) and 12].
22. 3 (appropriate for water). This procedure also accounts approximately for (mild) changes in dielectric screening (see text) on the relative band intensities upon coadsorbate removal. Further details of the calculational procedure can be found in Ref. 6 (a).
