Aqueous layer infrared reflection-absorption

The absorption and emission spectra of Ru(bpy) + also showed pronounced spectral shifts (compared to that in water) upon intercalating into a sulfonated derivative of layered a-ZrP, zirconium sulfophenylphosphonate, or ZrPS [84], The XRD and the infrared (IR) spectra of the mixture, on the other hand, indicated that the chemical and structural characteristics of the complex were not significantly affected by the host matrix. The diffuse reflectance spectra, however, revealed three important differences from that observed in aqueous solution. These are that (1) the tt-tt band was strongly red-shifted to 317-320 nm from that observed at 285 nm in aqueous solution, (2) the MLCT band also red-shifted, depending on the loading, from 462 to 494 nm, and (c) the ratio of the intensity of the tt-tt band to the MLCT band decreased with loading (Fig. 40).
