A natural abundance (77)Se solid-state NMR study of inorganic compounds
Abstract:
Various inorganic selenium-based compounds were analysed by (77)Se solid-state NMR, and a distinct difference in chemical shift ranges for compounds where selenium is present as selenide (Se(2-)) ionically and covalently bonded systems was observed. The selenides exhibit a shift range of approximately -700 to -100ppm, as opposed to 700 to 1600ppm for the compounds where there tends to be more direct covalent bonding to the selenium. The anisotropic hyperfine shift observed in NbSe(2) is shown to be axially symmetric, where the H(11) component is found to be normal to the Se3-trigonal plane.

The internal reference compound generally used in NMR spectroscopy is tetramethylsilane (TMS). TMS is preferred because it is chemically inert, soluble in NMR solvents, and easily removable. Also, the highly shielded methyl protons in TMS yield an intense...
