THE INFRARED PHOTODISSOCIATION SPECTRA OF FE-N(CH3OH)(M) COMPLEXES AND THEIR DEUTERATED ANALOGS NEAR 10-MU

摘要

The infrared photodissociation spectra of Fe-n(CH3OH)(m), Fe-n(CH3OD)(m), Fe-n(CD3OH)(m), and Fe-n(CD3OD)(m) (n = 5-15; m = 1,2) have been recorded from 920-1090 cm(-1). Analysis of the spectral features indicates that in all cases, molecularly adsorbed methanol is the absorbing chromophore, with no evidence of methoxy formation. The observed frequencies for the C-O stretching vibration and other vibrational modes are shifted similar to 40 cm(-1) to the red of the corresponding fundamentals of gas-phase methanol. The spectral shifts and thus the magnitude of the cluster-methanol interaction are observed to be independent of iron cluster size over the size range studied, implying an insensitivity of the interaction to the underlying cluster structure.
