Conformation of cis-2-butenedialdioxime, a newly synthesized compound, was assigned by means of nuclearmagnetic resonance, extended Huckel molecular orbital method, and Pople's model of anisotropic effect. It was confirmed that two carbon-carbon single bonds are conrotatorily twisted from the molecular plane of six sp2 orbitals of carbon-carbon double bond. The conformation of minimum energy is found to be twisted by 25℃.
