Nuclear magnetic resonance spectroscopy. Use of carbon-13 spectra to establish configurations of oximes

The use of ^(13)C nmr (cmr) spectra for the determination of configurations of oximes is described. The problems of quantitative analysis of syn-anti mixtures of oximes by cmr, because of differential T_1 and Overhauser effects, are considered. Chemical shifts for the cmr resonances of a number of aldehydes and ketones are reported
