The relationship between the sites that bind metal ions has also been studied,1319 using 31P and 113Cd NMR spectroscopy these techniques have provided valuable information on the influence of metal-ion binding, cooperativity and phosphate binding. ...

While only a little useful nmr work can be done on compounds of either Zn or Hg, 113Cd has proven to be very practical for nmr studies.3... 

Another DMS having a WZ structure studied by 113Cd MAS-NMR is Cd xMxSe (M = Co, Fe), where assignments were made to specific NNN M-S-Cd-S-Cd conformations [251]. In the case of Co++ substitution, however, the... 

Alloys of ZnxCdj xS with Cd-rich inner cores and Zn-rich outer shells have also been studied by 113Cd MAS-NMR. CP-MAS-NMR was used to identify surface 113Cd nuclei, which were shifted to much lower frequency [326]. 

Nanoparticles of dilute magnetic semiconductors have also been studied by NMR. Here one important question is whether the magnetic ion is incorporated into the NC or resides on the surface. The 113Cd MAS-NMR of NCs of Cd0.991Co0.009S with diameters from 3.5 to 29.5 nm showed peaks shifted by electron hyperfine interactions from next-nearest neighbor Co2+ ions, and by comparison with results from bulk samples that were discussed in Sect. 3.5 it was concluded that Co2+ ions occupied Cd2+ sites and were distributed homogeneously ... 

A fairly recent development in zinc and cadmium chemistry has been the use of NMR to study the coordination environment of these metals 1L1Cd, 113Cd and 67Zn nuclei have been A structure-reactivity relationship which predicts formation constants of complexes with organic ligands has been put forward.241 ...
