A Study of X-Ray Absorption Edge Spectroscopy as a Tool for Solid-State Chemical Research

摘要

Progress in the following areas is reported (the first 3 items are summarized briefly - a detailed report having been given in AD-610 719): (1) Design and development of a novel monitored beam x-ray absorption spectrometer arrangement to solve the intensity stabilization problem. (2) Observation of covalency effects in the spectrum of several copper compounds. (3) Investigation of valence changes associated with conductance and magnetic anomalies in LaCoO3. (4) A study of the sensitivity of absorption edge position to valence in a series of iron compounds. (5) Investigation of the tetravalent oxidation state of iron. (6) Investigation of 'white-line' spectra in some cyanides and study of relative intensity fluctuations with bonding 'p' character. (Author)
