## Abstract Carbonβ13 shielding tensor data for eight metal acetates, obtained by analysis of spinning sideband manifolds of slowspinning CP/MAS spectra, are presented and discussed.
The orientations of the principal axes of the 13C chemical shielding tensor of the double-bonded C5 carbon nucleus in smgle crystals of 1,1,2,2-tetraacetylethane are essentially identical with those of an aromatIc carbon nucleus. That observation and the similarities between the tensors of the carbo
The principal elements of 13C chemical shift tensors in some dicarboxylic acids were determined from powder samples by two methods: (i) from the theoretical fit of the experimental data and (ii) from the sideband intensities of the CP-MAS spectra using the graphical procedure of Herzfeld and Berger.
