Fig. 5: Electronic band structure and calculated optical absorption spectra of the gold hydrides.

a The band structure of the mono hydride AuH (\(F\bar 43m\)) drawn together with the graphs of the density of states (DOS) mapped onto the same energy (vertical) axis. b The conduction band (d-, s- bands) and the first 3 unoccupied bands are highlighted. The DOS-s are shown separately for Au 5d, Au 6 s, and H 1 s electrons to help interpretation of the band structure. The inset in the graph of the DOS shows the simulated optical absorption spectrum of AuH. c The calculated absorption spectra for the gold hydrides, the spectra are offset for clarity; the measured data are shown by the gray markers.
