Abstract

A linear relationship has been found to exist between the aluminum‐27 and gallium‐71 NMR chemical shifts of a series of structurally analogous aluminum and gallium compounds having only oxygen in the first metal coordination spheres; δ^71^Ga = 2.83(δ^27^Al) − 4.50. This relationship allows the prediction of ^71^Ga chemical shifts for such gallium compounds from the ^27^Al values already known for their aluminum analogues, and also a greater understanding of observed ^71^Ga chemical shifts.

An empirical correlation between the peptide ~SN chemical shift, 6~SNi, and the backbone torsion angles t~i , gti\_ 1 is reported. By using two-dimensional shielding surfaces A(l~i,/l/i\_l) , it is possible in many cases to make reasonably accurate predictions of lSN chemical shifts for a given stru
