Infrared spectroscopy of metal cluster-adsorbate complexes: Fen(CH3OH)m revisited

The infrared multiphoton photodissociation spectra of Fe8(CH3OH)m complexes, formed via reaction of Fe8 with methanol, have been recorded near 10μ using a continuous wave, line-tunable carbon dioxide laser. Depletion features observed near 990 and 1070 cm−1 are generally consistent with the observations of Zakin et al. [J. Chem. Phys. 85 (1986) 1198]. Spectra recorded using deuterium-substituted methanol, CH3OD, CD3OH, and CD3OD indicate that methanol adsorbs nondissociatively to small iron clusters at 77 K.
