Nuclear resonance vibrational spectroscopy : ウィキペディア英語版 | Nuclear resonance vibrational spectroscopy Nuclear resonance vibrational spectroscopy is a synchrotron-based technique that probes vibrational energy levels. The technique, often called NRVS, is specific for samples that contain nuclei that respond to Mössbauer spectroscopy, most commonly iron. The method exploits the high resolution offered by synchrotron light sources, which enables the resolution of vibrational fine structure, especially those vibrations that are coupled to the position of the Fe centre(s).〔E. E. Alp, W. Sturhahn, T. S. Toellner, J. Zhoa, M.Hu, D. E. Brown. "Vibrational Dynamics Studies by Nuclear Resonant Inelastic X-Ray Scattering" Hyperfine Interactions 144/145: 3–20, 2002.〕 The method is popularly applied to problems in bioinorganic chemistry,〔W. R. Scheidt, S. M. Durbin, J. T. Sage, "Nuclear resonance vibrational spectroscopy – NRVS", J. Inorg. Biochem. 2005, vol. 99, 60-71. 〕 materials science, and geophysics. A novel aspect of the method is the ability to determine the 3D-trajectory of iron atoms within vibrational modes, providing a unique appraisal of DFT-prediction accuracy.〔J. W. Pavlik, A. Barabanschikov, A. G. Oliver, E. E. Alp, W. Sturhahn, J. Zhao, J. T. Sage, W. R. Scheidt, "Probing Vibrational Anisotropy with Nuclear Resonance Vibrational Spectroscopy" , Angew. Chem., Int. Ed. 2010, vol. 49(26), 4400-4404.〕 The other names for this method include nuclear inelastic scattering (NIS), nuclear inelastic absorption (NIA), nuclear resonant inelastic x-ray scattering (NRIXS), and phonon assisted Mössbauer effect. ==References==
