In this article we revisit our recent picosecond and femtosecond X-ray absorption spectroscopy (XAS) emission (XES) experiments, probing the ultrafast electronic geometric evolution of photoexcited haem proteins, namely ferrous Nitrosyl Myoglobin (MbNO) ferric Cytochrome c (Cyt c). We show through these two examples, combined with results from optical spectroscopy, universal behavior excited st...
We present resonant inelastic x-ray scattering and x-ray emission spectroscopy results on Gd metal to 113 GPa which suggest Kondo-like aspects in the delocalization of 4f electrons. Analysis of the resonant inelastic x-ray scattering data reveals a prolonged and continuous delocalization with volume throughout the entire pressure range, so that the volume-collapse transition at 59 GPa is only p...
X-ray absorption near edge structure Fe K-edge spectra and Fe Mössbauer spectra of selected standard compounds were recorded at room temperature. Valence and spin states of Fe in these samples known from Mössbauer spectroscopy were correlated with the shapes of X-ray absorption near edge structure spectra in search of possible application of X-ray absorption near edge structure spectroscopy as ...
