The most common source for this technique consists of a cobalt atom whose decay eventually emits a 14.4 kilo-electron-volt ray.
This technique can be used to determine the oxygen environment of heptaÂ·valent neptunium compounds, in particular whether oxygen ligands are bridging or not. Compounds that can be analyzed with this technique can have their vibrational energy levels probed with NÂ·RÂ·VÂ·S. Spectra in this technique typically consist entirely of a doublet or sextet. The source for this technique must be moved to prevent it from being monochromatic, which is why shifts in this technique are measured in terms of millimeters per second. The most common source for this technique consists of a cobalt atom whose decay eventually emits a 14.4 kilo-electron-volt ray. Like NMR, this technique obtains information about the nucleus, as information about oxidation state and spin state can be obtained from the isomer shift and quadrupole splitting. For 10 points name this form of spectroscopy primarily used to study compounds containing iron-57, which relies on the recoil-free absorption of gamma rays.
