The x-ray-absorption near-edge structure (XANES) of sulfur hexafluoride, {\mathrm{SF}}_{6} in the gas phase has been measured with high energy resolution at the sulfur {\mathit{L}}_{2,3}and fluorine K ionization thresholds using synchrotron radiation from the SX700/II monochromator at BESSY. Besides dominant transitions to core-excited inner-well states, several series of Rydberg states with vibrational fine structure were resolved below...
