isotropic component/ A7660C Chemical and Knight shifts (condensed matter NMR)Nuclear magnetic resonance of 31P measurements have been made for UPY (where Y = S, Se and Te) compounds. The resonane lines show the effect of anisotropic Knight shifts. In the UPS, the NMR data indicate an ...
The primary references for these values are: 1) the 1991 Bruker Almanac, and 2) Compilation of reported F19 NMR chemical shifts, 1951 to mid-1967 by Claude H. Dungan and John R. Van Wazer. Negative shifts are those that appear upfield of CFCl3 and positive shifts are those that appear...
