The spectrum simulated with Lorentzian functions is overlaid with broken lines. The pNB-adsorbed surface was irradiated in air with p-polarized pump (8mjcm ) and p-polarized probe (8mjcm ) pulses of a 550-nm wavelength.

The structure is called an APB (anti phase boundary) or twin structure, and is similar to the shear structure of (110)j[li0] of ReOj (see Fig. 2.6(a)). Note the atomic arrangement in the zones framed by dotted lines (see also Fig. 2.113).

The molecule is reformed after desorption of the CO at 450K following exposure to lOOL of CO (b). Reaction of Rh(CO)2 with hydrogen forms the monocarbonyl Rh(H)CO [71].

One may have expected that the transmission band should remain invariant with (j), since P couples to Vsym(OCO) of both species equally at all ( ). In fact the doublet structure in the transmission band was ascribed to the presence of the two formate species. However, while species A has C2V symmetry, the symmetry of formate species B is lower because of the incorporation of one of the formate oxygen atoms in the TiO2(110) top rows (Figl4). The result is that Vsym(OCO) for B also has a component parallel to the surface which can couple to Pt, resulting in an absorption band. This coupling is possible at (j>= 90°, but not at ( )= 0°, resulting (because of its coincident energy) in the apparent (j) dependence in the Vsym(OCO) transmission band.
