Assignment of fine structure in the HBr absorption spectrum at the Br3d→Rydberg resonances using the Auger resonant Raman effect

X-ray absorption fine structure XAFS spectroscopy has been used to determine the valence system for the Fe atom in ilmenite, FeTiO3 . This is the first XAFS data in FeTiO3 to our knowledge. The α- Fe2O3 data served as the standard in determining the ionization of the Fe atom in FeTiO3 . Observation of intensity and k-space are consistent. There was no evidence of mixed valence on comparing the FeTiO3 near edge X-ray absorption spectrum with α- Fe2O3 data. The absorption spectra suggest that iron is in the trivalent state in ilmenite.

Electronic And Vibrational Spectra

The infrared spectrum of fulvene has been observed from 250 to 4000 cm-1 in the gas phase, and as a glass and a polycrystalline layer at liquid nitrogen temperature. On the basis of gas-phase contours and P-R separations 14 of the 30 fundamental vibrations have been assigned. The electronic absorption spectrum of fulvene has been recorded from 400 to 167 nm in the gas phase and four electronic transitions have been identified. The lowest-energy transition was found to be broad and structureless while the three higher-energy transitions showed an extensive vibrational fine structure. The electronic transitions have been tentatively assigned on the basis of VESCF-MO calculations and a partial analysis of the vibronic structure has bees made.
