## Abstract This paper presents novel measurements and calculations of the olefinic ^13^C chemical shift tensor principal values in several metal diene complexes. The experimental values and the calculations show shifts as large as 70 ppm with respect to the values in the parent olefinic compounds.
In high-resolution solidstate CP/MAS 13C NhfR spectra of several hydrosybenzaldehydes, the downfield shifts due to hydrogen bonding for the carbonyl carbons are found to vary inversely with the O...O hydrogen-bond distances\_ Conformations of the aldehyde groups in the solid state are determined by
