TL;DR: In this paper, the authors used infrared spectroscopy to study the mechanistic details of adsorption and photocatalytic oxidation of acetone on TiO2 surfaces at 298 K. Infrared spectra at low acetone coverages (θ < 0.05 ML) show absorption bands at 2973, 2931, 1702, 1448, and 1363 cm−1 which are assigned to the vibrational modes of molecularly adsorbed acetone.
