Infrared spectroscopy of metal cluster-adsorbate complexes: Fe n(CH 3OH) m revisited

Abstract

The infrared multiphoton photodissociation spectra of Fe 8(CH 3OH) m complexes, formed via reaction of Fe 8 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, CH 3OD, CD 3OH, and CD 3OD indicate that methanol adsorbs nondissociatively to small iron clusters at 77 K.
