IR spectra of H-MOR sample after pretreatment at 500 C and after adsorption desorption of ammonia at 150 C. All spectra recorded at 25 C.

IR spectra of H-p after loading with increasing amount of 1 1 propene enzene mixture at 295 K.

IR spectra of H-P after loading with increasing amount of 1 6 propene benzene mixture at 295 K.

IR spectra of H2 adsorbed at 77 K on decationated mordenite .

IR spectra of H2 chemisorption complexes obtained after H2 addition to a previously dehydroxy-lated sample of MgO nanoparticles.

IR spectra of H3PW12O40,

IR spectra of HA, in its dried state . The hydration spectrum labelled Hy-D-0.73 W is equal to the subtraction to spectrum Hy of spectrum D and spectrum Wmultiplied by a coefficient equal to 0.73, which ensures the disappearance of the narrow bands due to water vapour. These bands are shown in spectrum W, which is the spectrum of the cell without sample but with an atmosphere with calibrated water vapour pressure p.
