There has been an ab initio calculation of 77Se chemical shifts for SxSe4 x2+ (where x = 0-3).834 The 77Se NMR spectra of PhSeCH = C(SePh)R (R = [Pg.59]

Only for three selenete complexes 12a, 12b, and 18 have 77Se NMR data been reported <1995CC2461>. The chemical shifts of 77Se NMR spectra in the selenetes are compiled in Table 4. [Pg.468]

Another study of the surface structure of CdSe NCs of 3.7 nm size used 31P MAS-NMR and 31P/77Se rotational-echo double-resonance (REDOR) to identify overlapping broad peaks from two surface species trioctylphosphine oxide (TOPO) at 29.3 ppm and trioctylphosphine selenide (TOPSe) at 22.2 ppm [343]. Both the isotropic chemical shift and CSA of the surface-bound TOPO were substantially different from those of the free ligand. Spin-echo experiments on 31P were stated to indicate an average P-P distance of 8-10 A at the surface, consistent with capping at alternate atomic sites (all Cd but not Se). [Pg.293]
