MOLECULAR STRUCTURE AND CONFORMATION OF 1,2-DIMETHYLHYDRAZINE STUDIED BY GAS ELECTRON DIFFRACTION

Abstract An electron diffraction study has shown that the inner–outer conformer of 1,2-dimethylhydrazine, the C–N–N–C dihedral angle being estimated to be about 90°, is a major conformer in the gas phase. Another conformer is found to have a smaller dihedral angle (inner–inner form). The thermal-average bond distances and angles of the inner–outer conformer have been determined.
