Abstract
High-resolution 13C NMR spectra were measured for the CH3–C(=NOH)–C(=NOH)–R (R=CH3, C2H5, n-C3H7, and n-C4H9) series in the solid state. A commercially available powder, dimethylglyoxime (R=CH3), produced two C2 signals, indicating two isomers: i.e., s-trans-(E,E) and s-cis-(E,E). The ratio of trans: cis was estimated to be 3:1.Keywords
