3.1.2 CO adsorption on reduced sample. We have reported in Fig. 2 the IR spectra obtained after CO adsorption under saturation conditions (P CO = 0.7 kPa) and then evacuation at room temperature on the sample reduced at different temperatures. In the spectral region of the ν (CO) vibration, the recorded spectrum of Pt/CeO 2 -R 423 E 673 sample presents several bands at 2096, 2061 (shoulder Abstract. Bands due to the in-plane bending mode of hydrogen-bonded surface hydroxy groups are observed on alumina, zirconia, magnesia and thoria samples. Their assignment is based on the effect of dehydration by heating under evacuation, and isotopic exchange using D 2 O and H 2 O 18. The observed frequencies are apparently related to the April 10, 2024 at 9:14 p.m. EDT. Community members react after a shooting in the Carver Langston neighborhood of D.C. on Wednesday.
