energies of new N,N carbonyl dipyrrinone‐derived oxime molecules (E/Z‐s‐cis 4a and E/Z‐s‐cis 4b) have been investigated. The calculated energies, molecular geometries, and 1H/13C NMR chemical shifts agree with experimental data, and the results are presented herein. The E‐s‐cis conformations of 4a and 4b and the Z‐s‐cis conformation of 5b were found to be the thermodynamically most stable isomers with the
