Sideband pattern index

Constant in Eq. (1) - for interpretation see text Sideband pattern index Isotropic chemical shift... 

To acquire better structural information, one has to resort to more advanced solid-state NMR techniques. Here, they will be reviewed by subject rather than in chronological order. First, we shall briefly look at P relaxation. Second, components of the H—> P CP signal will be discussed. Third, much attention will be given to HPO detection by differential H—> P cross-polarization (DCP). Then the P sideband pattern index and chemical shift anisotropy in the study of bone calcification will be briefly reviewed. Finally, a special ADRF-CP technique will be mentioned. 

Fig. 16a-f Conventional CP/MAS NMR spectra of various species related to the early stages of mineralization (162 MHz for P, MAS at 4.5-5 kHz) [43]. The spectra show that the sign of the sideband pattern index is indicative of the Ca + complexation...
